After setting up a BIND DNS on my Ubuntu 10.04 x32 server, I decided I should probably make a mail server too. I wanted to be able to access the mail from my iPhone.<\/p>\n
Postfix was installed by default as I needed sendmail for some other php scripts I had previously written\/edited. Otherwise you can always I let webmin install dovecot for me. Dovecot is a POP3\/IMAP server that will communicate with postfix’s mail system. Basically it’ll read the mail from \/var\/mail (which I had to edit – more on that later). I then set the DNS name for mail.mydomain.tld using BIND on webmin.<\/p>\n Use webmin and open up Servers > Dovecot Then I made sure that port 110 was opened up on the firewall and away I went. I could now connect to the server via POP3 on the iPhone and retrieve my mail. However, I could not send mail. The fix for that (Found from Jimmy’s Weblog<\/a>): START=yes pwcheck_method: saslauthd<\/p><\/blockquote>\n smtpd_sasl_auth_enable = yes \/etc\/init.d\/postfix restart Honestly by that time I had changed a few other things in the postfix configuration, so hopefully this still works. If I ever set it up again or do a dry run on a secondary test system (ie if I find the time to QA my own work) then I will most definitely put up any updates. Any issues let me know.<\/p>\n","protected":false},"excerpt":{"rendered":" After setting up a BIND DNS on my Ubuntu 10.04 x32 server, I decided I should probably make a mail server too.
