I just installed CentOS 5 + Postfix + Dovecot. Now When I send mail via telnet from one user to another via Postfix (MTA), I have no problem. The recipient gets the message perfectly. Now this tells me that Postfix is working fine (I assume) but then I configured Dovecot to use IMAP4 and then configured my Thunderbird client. Now all the messages I previously sent using Telnet showed up in Thunderbird Inbox but then when I attempt to send a message via Thunderbird, the message appears to send fine however the recipient never gets it and I get no delivery failrures back of any kind. I check the Postfix (MTA) mail queue and it shows empty. What is causing this anyone? Does anyone know why this is not working?
Here is my postconf -n for Postfix (MTA)
[root@nat home]# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 home_mailbox = mail/ html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = wtf.com myhostname = nat.wtf.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP $mail_name unknown_local_recipient_reject_code = 550
================================================================
Here is what is 'UNCOMMENTED' in my /etc/dovecot.conf
protocols = imap imaps mail_location = maildir:~/mail protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh } login_process_size = 64 protocol pop3 { protocol lda { protocol lda { postmaster_address = carlos@wtf.com } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { }
Anyone know what is causing this problem above? Sending internal email works fine via Telnet however when I try using my mail client / imap4, nothing happens.

I did and was told this appears to be a Dovecot config issues since the MTA (Postfix) is sending mail just fine via Telnet. What makes you suggest this to be a MTA issue?

Dovecot does not speak SMTP to other mail servers, unless you mean "send mail" in a different sense than I'm used to.

I mean that I can send (SMPT) via Telnet which Postfix does fine. However when I configure Thunderbird mail client to use the IMAP (Dovecot) settings and attempt to compose a new message, the user (recipient) never receives the message. I am thinking as well as users of the Postfix list that this issue is related to my Dovecot config file not being properly set up. I could be wrong...
In this case telnet is an SMTP client and Thunderbird is an SMTP client. One works and another does not. Seems like a client issue to me. IMAP has nothing to do with sending email except that maybe a copy of your sent message may get stored on the IMAP server under a "Sent Items" folder. I would check your postfix logs.

Then it's a Thunderbird configuration problem.

Dovecot has nothing to do with sending mails. The closest it comes to is when TB saves the sent message to "Sent messages" mailbox (or whatever it is configured to use).

Thunderbird is connecting via SMTP to your Postfix installation to send; Dovecot only does the POP3/IMAP half.

Thanks all. It appears that it is an issue with Thunderbird. Looks like it's working well. Thanks for the help and pointing me in the right direction!

I think it also helps if you have the output of dovecot -n
1.0.7: /etc/dovecot.conf
