Ubuntu Networking :: Configure Postfix As Localhost Smtp Server And Send Email?
May 25, 2010
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:
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
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.
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..
Jun 2 21:19:51 microtontech postfix/smtp: connect to k.mx.mail.yahoo.com[188.8.131.52]: Connection timed out (port 25) Jun 2 21:20:10 microtontech postfix/smtp: connect to
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..
In my Windows environment, I use email client such as Microsoft Outlook to connect to our email server to send email with the following configuration:
Incoming server (POP3): 995 - (requires with SSL) Outgoing server (SMTP): 465 - (use encrypted connection SSL)
And the mail server requires user ID login and password.how do I setup a text command based email client in my Linux (Centos 5.1) to send out email through the existing email server above, which is in another machine? The email client has to be text command based because I need to use command line to send notification email from anothar application installed in my Linux (Centos 5.1) Since the email client will only be used to send email notification, I don't require setting up of an email server in my linux.
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. "

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 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) Code: Dec 7 17:44:42 homer dovecot: imap-login: Login: user=<scarleo>, method=PLAIN, rip=18.104.22.168, lip=192.168.0.18, TLS Dec 7 17:44:42 homer dovecot: imap-login: Login: user=<webadmin>, method=PLAIN, rip=22.214.171.124, lip=192.168.0.18, TLS Dec 7 17:45:16 homer postfix/smtpd: connect from bredband.comhem.se[126.96.36.199] .....
i need to configure postfix on centos to relay email from the internet to the Exchange Server and i also need that emails sent from the exchange within the same domain be sent to postfix then resent to exchange because i have spamassassin and clamav installed on centos to filter all incoming and outgoing mails ...
I have CentOS 5.3 ISPConfig 3 installed. I have noticed that some mail I sent out were lost. Expecially, email with subject like "a" or "aa". I think Amavis block my email. Please tell me how to configure amavis to allow all outgoing email by postfix?
I'm not trying to setup a email server. ;) Firewall is set to disabled. SELinux is set to disabled.. How can i configure (which file?) the server to be able to send email out? When I try "mail -s testmail myemail@[URL]" and enter some text and then CTRL+D.. and return, I get command prompt again..
I have an issue with sendmail. I need to configure sendmail to send email from command prompt to any domain. This is just for the notification purpose. I installed sendmail and sendmail-cf and sm-client. The following are the configuration I have done.
I'm rather (VERY) inexperienced when it comes to Linux, but Fedora 14 is the environment I have to use on my laptop at work, so please forgive any dumb that comes out of me.
How do I tell php to send an email with mail() using an external mail server?
The situation: I've got apache/php running a webserver on my local machine. It's for dev purposes only, and the website files I'm using are checked out from our SVN. This lets me make changes to our website while not actually changing our website.
I've come across an issue I'm fixing where I need to verify that an email is successfully getting sent out, and unfortunately, this email is sent out using php's mail(), and not our website's usual $mail object. Unfortunately, I don't have the authority to change how this sends out right now, just when it sends out.
I've been running everything fine on my machine for a month now, and haven't needed the mail stuff until now. How do I tell php to send an email using an external server?
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
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.
I'm running SUSE linux Server version 11. I want to configure mail server with postfix & cyrus-imap. For that, i have read many documents in Internet by i met issues. I'm running DNS in this server & it's ok Now I cannont send mail through command line.
We host our own mail server on our Fedora box. We would like for our field people using there smart phones to be able to send and receive mail. Receiving is no problem but sending creates problems with relaying and port assignments. Is there any way sendmail can be configured to allow these mobile phone users (AT&T, Verizon) to send mail through our server?
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 a website sitting on my private server (CentOS 5x) running plesk 9.2.2. There is a form for customers to fill out and when they press send it sends the data to a specified email address and a BCC if desired (email address present in BCC Field) and and response to the person submitting the form. The problem I am having is everyone gets their email after the submit button is pressed except the person listed in the TO field. Below is the output from postconf -n and below that is the maillog
After a reboot of my VPS, I keep getting the following error when sending email to my domain (hosted on Google Email). I can send to other email addresses but my own. So it seems like postfix thinks all mydomain.co.nz is to be sent internally?
