Ubuntu Servers :: Postfix 'status=bounced' Unable To Send Email To A Domain?
Sep 8, 2010
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?
Sep 9 09:25:05 mydomain postfix/pickup[20784]: 0316C3CC68: uid=1000 from=<sidb>
Sep 9 09:25:05 mydomain postfix/cleanup[20806]: 0316C3CC68: message-id=<20100908212505.0316C3CC68@mydomain.co.nz>
Sep 9 09:25:05 mydomain postfix/qmgr[20783]: 0316C3CC68: from=<sidb@mydomain.co.nz>, size=326, nrcpt=1 (queue active)[code].....
How do I tell postfix that mydomain.co.nz is to be sent to Google email server?

I am thinking about buying a domain name and hosting my web server.
I have seen pricing from $8 to $30 a year. Any favorites from fellow ubunters? Also this whole "whois" thing scares me, if I am correct my information I enter when buying the domain is enter into some big pool of information. People can find this information out and dig up important information. url Can I prevent this with private Whois or how do I set it up? This website examples some of my fears with this whole WhoIs thing, url whois/Private-Whois.html Does most/all domain registers come with email or just email forwarding or both? How does that work? At this moment, my only question about Web Hosting is how do I get Website Statistics as in: Stats, web analytics, web traffic stats and more? I will be web hosting through Ubuntu 9.10 gnome.

I have some scripts that do usual stuff like backing up MySql database, gz, tar some files and put them on FTP or sync with some other backup/mirror system. Some scripts are running quite frequently (like twice/thrice per hour). I am sending email with attached log output from commands after completion of job. It is quite a lot of email to keep track of.I want to send email only when script fails to do something, that is when some command in script fails. How can I accomplish this?

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 just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being user@mydomain.biz it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my main.cf. I am running ubuntu 9.10.# See /usr/share/postfix/main.cf.dist for a commented, more complete version# Debian specific: Specifying a file name will cause the first# line of that file to be used as the name.

I want two alias functionality:
1. when a mail is sent to an account; if it has a forwarder set; it should forward a copy of email to the mentioned email address.
2. all the emails sent to a domain alias should be automatically forwarded to the respective email account in the main domain.
eg for 1. xyz@abc.com => hfg@gmail.com
eg for 2. xyz@alias.com => xyz@maindomain.com
We have a database that stores the mailboxes as we have our own control panel. I can get only one working at a time. I have the mysql query in the .cf file and mentioned it in the main.cf as 'virtual_alias_maps' but i need both to work not just one at a time.

I have an email setup where all of the emails from our email host is downloaded to our Linux server using Fetchmail. Then some of the incoming emails are sent to an MS exchange server (server1.domain.com) using Postfix. What i want to do is to send a copy of all emails to Another server (server2.domain.com) for redundancy.Can postfix be configured to send copies out to both?

I've just setup a new Ubuntu 10.04 LTS server on linode for myself. Followed an excellent instruction at: here to finish the installation of some basic stuff including postfix.
I am trying to figure out a way to send an email to my gmail address with an attachment, but cannot find how. Already confirmed that email can reach my gmail account.
In the end I have to use mutt to send the email with attachments, probably SendEmails will also do well, but I am wondering how to do the same thing in postfix from command-line?

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
[root@usloft1105 ~]# postconf -n

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).
Postfix details:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
body_checks = regexp:/etc/postfix/mbl-body-deny
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
[code]....
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=96.136.112.229, lip=192.168.0.18, TLS

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.
/etc/mail/sendmail.mc
1) dnl # DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
2) m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
3) /etc/hosts = 127.0.0.1 localhost.localdomain
/etc/hosts = 192.168.2.50 mysystem
4) /etc/hosts.allow = sendmail:ALL

I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.

I'm trying to figure out how to access the local part and the domain part of an email address in postfix's main.cf. For example, myname@mydomain.net has myname as the local part and mydomain.net as the domain part.I get the whole email address with %s. I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.

I'm running ubuntu 10.04 as a server that hosts a website and our email. I set up the email (Postfix) to work with Dovecot to enable IMAP and POP support.The mails can be retrieved and sent through this server with no hassles. We just have an issue that all emails sent via a client to any other address (be it on the same domain or not) will return to the inbox of that client.So basically, I open MS Outlook. Click new message and send it off to my GMail address. After I send it, it pops into my inbox on Outlook (stating that it came from me). The intended recipient also gets the message.
