Server :: Postfix - One Account Cannot Send / Receive Email (Other Works Fine)
Dec 7, 2010
I just set up a new email server on Debian Lenny. It's Postfix for MTA and Dovecot for IMAPS server. I use Dovecot for authentication. I have two UNIX users on the system (except root), one was added before the installation of Postfix and Dovecot. I'm not doing any virtual things, just plain UNIX users and one domain on a dynamic IP. The first user, "webadmin" can send and receive emails just fine through the server from my mail client.
Now I just added a new user, "scarleo", and it turns out I'm unable to send and receive emails with this account. If I log in (SSH) with scarleo I can use bash mail to send emails, works fine. scarleo can also receive emails from webadmin and can connect to Dovecot to read emails. However scarleo cannot send or receive to or from anyone outside the server from my mail client. I have restarted both Postfix and Dovecot after adding the user. Do I have to do something else to make this account work like webadmin's?
A few relevant lines from mail.log: (I've modded my real IP)

I've been trying to send mail to email account even after installing postfix but am not able to do so.My distro is Centos 5.4. I followed the Centos user guide to install and configure postfix into the server,
Code: http://wiki.centos.org/HowTos/postfix but still didn't receive any email.
I have configured Postfix on a Ubuntu 8.04 box using this tutorial:I can send emails but I cannot receive any email because of a "bad recipient address syntax:"The log from /var/log/mail.info says this:
How can I send email outside my LAN using postfix? Actually, I can received email from outside like yahoo. hotmail etc.. But when I am trying to send outside in my mail server here is the error I got..

I try to telnet yahoo.com and smtp.pldtdsl.net 25 here are the result, but when I try to telnet smtp.pldtdsl.net its showing trying only.. I checked if my ISP is blocking port 25 isn't. (I forgot what is the website I used to check if my ISP port 25 is block) I try already to used in my relayhost the [URL] but the email I sent still bouncing..But I remember last time when I was installed Hmailserver in my Win2K3 machine I sent email outside but I cannot received..
I'm experimenting with with mail-servers now and I'm trying to configure postfix to send emails from one email(pop3 is gmail) to any email outside the local network. Server is Ubuntu 10.10 with the last updates.
what do I need to change in postfix/ dns to send email to one one of the email server hosted by 1and1.
I'm using zenoss to monitor system/ network and devices. I wanted to setup email notification , so I installed postfix. All works fine when I use my private account on yahoo or hotmail. but when I specify email account that is hosted by 1and1 I receive error 421. "

I'm trying to configure postfix so smart daemon can send out notifications emails. My system will need to send emails to a mail server that is on the same local network. I have not had much luck in getting this to work, and am confused on what I need to setup to do this and how to set it up. Does my system need to be apart of the same domain as the mail server? If so, how do I do this? Is there any restrictions sending emails from the command line as the root user? Do I need to configure a relayhost?
Basically all I need to do is send emails to a local mail server, i.e. a mail server on the same local network. I do not need to receive emails. I am rather clueless as to how to set this all up, and what I need for this basic email functionality. I have read and tried many postfix configuration tutorials, but when I try to send out a test email to a email address on the local network mail server I always get "Connection refused" to the server and deferred or bounced status on my test email.
My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?
I got a request today from someone on the software development team that reads as follows: Quote: According to RFC 4409 client mail submission to an email server is supposed to use port 587. Server to server SMTP relays are to use port 25. When I am not on site, I can't email via my work account via my iPhone or my residential internet because my ISP(s) filter port 25 to only allow traffic to and from their mail servers. They do however allow 587 anywhere per RFC 4409. Just to send this email I am having to relay off my own server in California. get the proper ports opened on the mail server? [URL] So my question now is I'm wondering if my Postfix server isn't properly configured? Right now it's listening on the following ports:
I'm trying to set up a basic smtp server on my local computer that I can send basic, unencrypted email through on port 25. I installed postfix, and I chose the following options:
Internet Site, System Mail Name: localhost Root and postmaster mail recipient: I left this blank For other domains to accept mail, I entered : NONE, localhost No force synchronous mail updates Local networks: 127.0.0.0/8
the mail server itself will receive mail, that part works. i'm using dovecot imap to grab my mail, that works. but if i try to send mail from my iphone using an account on that server it doesnt work. this is what i see in syslog: May 15 07:14:52 coax postfix/smtpd: NOQUEUE: reject: RCPT from mobile-166-137-139-003.mycingular.net[18.104.22.168]: 450 4.1.8 <firstname.lastname@example.org>: Sender address rejected: Domain not found; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<[10.25.15.47]>
I have been running an email server on a Red Hat 9 system for 5 years, and wanting to upgrade it to the latest Fedora OS. A few days ago it crashed. The server is running Fedora 11 (up-to-date). Clients are Fedora 11 and Windows XP machines using Thunderbird for accessing email. The server is running Postfix and Dovecot. Within my local network I can send and receive emails. I can also send email to addresses outside of my local network. The only problem is that I cannot receive any email from outside the local network. I cannot think of anything aside from my firewall (iptables) or postfix config that could be causing the problem.
Below are my iptables file, and the postfix main.cf changes that I have made. Iptables (the same file I was using on Red Hat version 9 with one minor deprecated syntax changed): *nat :PREROUTING ACCEPT [22:1894] :POSTROUTING ACCEPT [14:840] :OUTPUT ACCEPT [17:1356] -A POSTROUTING -o eth0 -j MASQUERADE COMMIT *filter .....

I'm having trouble to send and receive e-mail using Thunderbird 3. When I tried setting up new account using the automatic configuration method,the result of scanning pop. and smtp. server returned 'none' with this orange circle. I assume it's the same problem that occurred when I first tried to install Evolution. But oddly,I manage to access the web-mail account provided by the ISP using the same information used to set-up Evolution and Thunderbird 3. Precisely I'm from Malaysia and the ISP is Streamyx.com. PC run on Ubuntu 9.10.And I've heard that the ISP is non-friendly of non standard e-mail applications.
I have a desktop that has been running Ubuntu for years. Finally I convinced my wife to get rid of windows XP and move to Lucid. I did a clean install of Lucid on her system writing over windows. After the install I installed Thunderbird using Synaptic Version 3.0.6 was installed on her system. On my desktop I am also running Thunderbird 3.0.6 We have several domains and mail servers on those domains.
They all use SMTP First, I installed the ISP email and that works perfectly. She can send and receive using our ISP's mail server. I then set up an email account in Thunderbird using the SMTP email server form one of our domains. She used to be able to send and receive from for one of our domains. She can receive email from that email server, but can not send (I can send and receive from the same domain using Thunderbird) Her SMTP and mine are set up identically:
Server Name: mail.[domain] Port: 50 Username: [user]@[domain] Secure Authentication: No Connection Security: No
She is able to receive email but when she tries to send. the connection in Thunderbird either times out. or gives a password error. The password is correct, because we can use Firefox, and go to the pop and log in.Also, she can receive email direct on her computer and has to log in using her password. So I opened Terminal and tested using:
telnet mail.[domain] 50
Trying [IP address] Connected to mail.[domain] Escape character is '^']'. 220 mail.[domain]
This leads me to believe something in Ubuntu is blocking her system from using Thunderbird to send emails through the email server. I've been at this for several days now. I did try totally un-installing Thunderbird using Synaptic. Then manually deleting the .Thunderbird file. Then doing a fresh install of Thunderbird using Synaptic. Still get the same results I am thinking that maybe App Armor is stopping this? Or perhaps some other security issue in Ubuntu like Linux Security Module? Otherwise the installation went flawlessly. We even got Skype working on the first try! Printers installed correctly and perfectly too.
I upgraded my home server from openSUSE 10.3 to 11.2. From that day, postfix rejects every email I try to receive by using fetchmail. The main.cf file was unchanged after the upgrade, postfix starts correctly, but it does not accepts emails! The errors I receive are:
Code: NOQUEUE: reject: RCPT from localhost[::1]: 504 5.5.2 <localhost>: Helo command rejected: need fully-qualified hostname; from=<> to=<email@example.com> proto=SMTP helo=
I have a very basic install of dovecot and postfix on the latest version of Ubuntu server. This is an internal only email server with internal only DNS. I can send email via clients and check said emails via the command line when logged in as the appropriate user. I cannot for the life of me check said emails via SquirrelMail on the server nor using IMAP clients. I have no idea where to look and I can't find a basic tutorial for the life of me. Where should I start?
I am would like to configure postfix to send and receive email across Ethernet (just for now). I have two machines with postfix installed both using Ubuntu 10.04 directly connected with an ethernet cable. I have successfully configured a machine to send email to gmail, however i have been unsuccessful in having these machines send email back and forth. I have been interested in setting up a little mail server at home and have just been trying some simple projects with postfix to start with. At this moment i am using ip addresses and am not concerned with using a dns server
machine A: has a fixed ip of 10.137.202.1, hostname = mail.me.com, machine B: has a fixed ip of 10.137.202.20, hostname = mail.ubuntu.com in the /etc/hosts file I map each hostname to ip address receptively (not sure if a good idea, but at this point I have been trying everything)
So I will execute from Machine B echo "Here is a message" | mail -s 'Hello' firstname.lastname@example.org
I currently get from mail.log timed out while receiving the initial server greeting. I get from mail.err valid hostname or network address required in server description #[10.137.202.1]. Obviously when I run the mail command from cmd user i do not receive anything. I can receive mail from myself if from machine A, I sent an email using the command above. I would just like to send email from machine B and receive it on machine A via direct Ethernet connection. I have been through postfix documentation and have also read the postfix definitive guide and have had no luck.
Here is a recent main.cf as I have tried getting this to work (this is for machine A however, similar for B)

nstalled Postfix + Dovecot + Roundcube on a plain CentOS 5.5 box, let say on "site.com".I cant send or receive emails. When I try to telnet from both localhost and from the outside world, it can not reach the mail server.Testing itself on port 25:
A bit clumsy subject, but I would like to make a script, which is able to send and receive email messages from CLI. The script should work like this:
1. read user input from stdin(for example a mail address) 2. send mail over SMTP(SSL, port 465) to a mail server 3. mail server sends an automatic response, script should just display this response email sent from mail server over IMAP(port 993)
At the moment I have a fallowing configuration in my Thunderbird:
I want to setup an email client in order to send/receive emails, but since i am experiencing some issues with my ISP, i decided to setup an SMTP server with Postfix on my machine.The problem is that i can receive emails but i can not send.I read almost every thread in here refering to Postfix, but i could not find the problem on my configuration.So here it is..
Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first
Currently i'm figuring out how to send email notifications to users when services went down in Nagios. I know i need to install and configure Postfix, which i did already. I assume that when i configured to point it to "Satellite mail system" is the correct one instead of other things like "Internet.." etc. So the configurations is when you have installed the Postfix and there would pop a lot of questions right? Other than that, what have i missed?
Oh ya, i remember something. Hmm. I do not have any so-called real smtp server so would that be alright? I heard that installed and getting the Postfix running would be enough as it serves as a MTA (mail transfer agent). So if i do not have any smtp server, the relay host= ' ' what should i put it as?
I am trying to setup a simple SMTP server to relay scanned documents from a Xerox machine to email addresses. Unfortunately the Xerox machine doesn't support TSL or SSL so sending mail over port 25 on gets blocked. I have setup postfix on a desktop running Fedora 13 and have been able to set it up to forward the mail onto the correct server (gmail for example). My question is, how do I get the server to encrypt the emails (scanned documents) when sending them over the internet?
I have tried adding:
Code: smtpd_use_tls = yes smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key But when I look at the wireshark capture of the sending I can read my test message in plain text.
