I don't know why but this is one of those things that I find extremely annoying to set up. Mainly because it often requires installing a full-blown MTA to do a much simpler job than it was designed to do. Unfortunately, ssmtp and exim, the only simpler ones, often suck (especially ssmtp, which even the maintainer gave up on). What follows is how I got postfix working on my Ubuntu Feisty machine (should work on more recent version of Ubuntu as well):
sudo apt-get install postfix sudo dpkg-reconfigure postfix
Here are the options to answer in order:
"satellite" (when given the list of configuration styles) <your normal user> (where to forward root's mail to) <your host name> <your ISP's smtp server> accept default (when asked what other domains to accept mail from) No (default is no synchronous updates on mail queue) 127.0.0.0/8 (accept default unless you know what you are doing) 0 (mailbox limit) + (default) all (default)
Reload or restart postfix, then do some testing:
sudo apt-get install mailx echo test |mail -s "test mail sent to external" <a href="mailto:me@gmail.com">me@gmail.com</a> echo test |mail -s "test mail sent to normal user" <normal user name> echo test |mail -s "test mail sent to root" root
You should get an email to your external address. And if you run
you should see 2 emails there for you, one that was sent to root (but was directed to you, see /etc/aliases for why) and the other that was sent to you.
To have those mails sent to an external address instead (like your me@gmail.com address) do the following:
echo me@gmail.com > ~/.forward
Update (2007-07-19): When I changed ISPs, my new ISP did not like my From: address being david@centurion (I just named it after the case model). So I had to do the following. Add this to /etc/postfix/main.cf:
smtp_generic_maps = hash:/etc/postfix/generic
Add this to /etc/postfix/generic:
@centurion <a href="mailto:david@telus.net">david@telus.net</a>
I just made up an email address there to make it happy.
Don't forget to run sudo postmap /etc/postfix/generic

error
I've got an error on the first message. The message is't delivered and I found a mail in my local mailbox with the following error message:
Diagnostic-Code: smtp; 554 5.7.1 : Sender
address rejected: Access denied
Any idea?
Thanks in advance

Your SMTP server is rejecting from: address
I think this is your smtp server rejecting the From: address. I have a solution for this as I recently had this problem with my new ISP. I'll put the solution up soon.

Thanks It worked like magic.
can I use it with LAMPP php program under ubuntu 8.10?
what is the minimal setup and php-ing I must perform so it will
send me an email using php (on my Lampp server with local host )? (at the first stage doesn't matter if it will
be tagged as spam on my gmail)
Thanks

SMTP Relay with Postfix or Exim4
Hi,
Am new to Ubuntu.
Tried your settings as mentioned above, i get this error when try to send mails from outlook express. Without relay i have to set 'my server requires authentication'.
Do i need to confiure something on this server.
The server is Ubuntu Server v12.0
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'mail.albateeltravel.com', Server: '192.168.1.5', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10053, Error Number: 0x800CCC0F
How can i resolve this so that the clients can send VIA this server and if possible change the port on the clients also so as to reduce spamming issues.
please help !

I think you're trying to do
I think you're trying to do something that is beyond the scope of this article. This article was just about sending mail from Ubuntu/Linux. It seems like you want to use your Ubuntu box to send outgoing mail. That is a much more complicated problem.

tested, works
Thanks for the writeup. I found the article by searching for "ubuntu testing mail" on google. I wanted to find a quick way to test mail sending from webapps on a host on a private network, without having to wade into docs for MTA's.
To confirm, I followed the outlined procedure on ubuntu 12.04. It worked without any problems. The setup just took a few minutes.

Good tutorial.
Good tutorial. I also wrote my own tutorial on configuring Ubuntu 12.04 with postfix and dovecot. It covers creating virtual mailboxes so you don't have to create new system accounts for every email address. Check it out: http://www.dev-smart.com/archives/492.

I can send email from my local domain at home using postfix
Hi experts,
I have a problem with email send back and forth. I can send email from my local domain at home using postfix, doveco in Ubuntu. When I receive my email from gmail and I tried to send back to see if I can receive from local email. gmail messaged that godaddy domain kicked back to gmail. I am currently purchased domain at godaddy but I didn't buy email from the domain yet. My friend said I can create it. Therefore, I got problem. For example, my domain name is abc.com where I bought at godaddy. My email at local at home is using info@abc.com. When I reply back to info@abc.com, the message deliver failure from godaddy sent back right away. How can I solve this method? Thank you very much for you help. Have a great day, experts.

I can now send email from my Macbook Pro using postfix/sendmail
Your article was great. I am now able to get the perl function working which I use to provide email notification of process progress on my system. This prevents me from having to login remotely to check progress. I was having issues getting past the reverse arp used by my ISP and configuring the smtp_generic_maps solved the issue for me. Thank you for a well written explanation.
