[Dovecot] Mail does not arrive at my server.

12:20 p.m.

I run under FC5. I want to setup a mail server with postfix (already runnung) and dovecot. Once this i working I add spamassassin and clamav. I setup postfix and can send emails. When replying to these emails they do not get to my server (I checked in the Maildir directory of the user, there is no file) The server has 2 NICs. there is a firewall where I opened the port 143 (that is for IMAP?) 0 0 ACCEPT tcp -- eth1 * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:143 flags:0x17/0x02

the only change I made to the dovecot.conf files is: protocols = imap

I did not touch the rest as in the comments of the file it says # Default values are shown after each value, it's not required to uncomment # any of the lines.

Any hint on what I am doing wrong is welcomed. Thanks in advance

You should better check your postfix logs and your postfix configuration.

Can you do IMAP queries?

Make sure procmail) delivers these mails : maildir, mbox, or /var/spool/mail

the mails reach your server at all (check your postfix logs)
to what type of inbox postfix or the local delivery agent (often

if dovecot looks in the right place (see above) for incoming mails.

Hope this helps,

Obviously, then, this is a postfix issue.

Dovecot is simply an IMAP/POP3 server, it is not responsible for accepting mail from the outside, that is the job of your smtp server, in your case postfix.

I suggest you go ask on their list...

Are you sure you have an MX record in the public DNS for your mailserver ? If not, outside mail will never reach you no matter what you configure on the server. It is not enough to have an open port 25 on yours server ! Anyway, dovecot is innocent here.

If no MX, mail servers should fall back to the A record.
