Try verbose_ssl = yes. This will make Dovecot log all the problems it sees with SSL connections.

In mail architecture like above, you need synchronize two configuration The format* and location of where postfix stores the incoming email The format* and location of where dovecot retrieves the email When they are out of sync, dovecot won't find email that previously stored by postfix. The related dovecot parameter is mail_location = ...

Use the recipient_delimiter directive in Postfix: recipient_delimiter = + There is no need to do configuration in dovecot.

I fixed it, but the fix wasn't so obvious. Having a missing postmaster_address setting was not the actual problem. dovecot-lda not looking at the correct config file was the actual problem. However the deeper problem seems to be this "feature" I randomly came across on Google https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/671065 where The ...

Here the proposed mail-flow-diagram for your case. External mail server | ▲ | | POP3 SMTP | | ▼ | Local mail server First, you need setup working local mail server with postfix and dovecot. The important parameter for postfix is never list your local domain in relay_domains. You can use virtual_mailbox_domains ...

Are you running with SELINUX enabled? If so, selinux may block dovecot from binding to another port and, after that, it re-bind on the default port (993). Try to temporarily disable selinux with setenforce 0 and to restart dovecot. Does that change anything?

Now, how do I create a chained ssl certificate for Dovecot, including domain1 and domain2? The term chained certificate is used when there are intermediates certificate between a certificate and the roots certificate. Your ultimate goal is providing dovecot service with SSL for multiple domain. Your current dovecot configuration is using default ...

The problem is the line: Apr 21 16:52:49 vultr postfix/qmgr[8072]: warning: connect to transport private/dovecot: Connection refused "Connection refused" indicates that there is no process listening to that socket, which is probably /var/spool/postfix/private/dovecot . As your postconf -M output doesn't list anything about dovecot you're missing a line in ...

Turns out i needed to change mydestination = localhost, localhost.localdomain, localhost, domain.com to mydestination = localhost, localhost.localdomain and leave home_mailbox empty.

I know, this is no real answer, but I can't comment at the moment. Sorry. This is a setting you can make in the virtual_mailbox_maps directive. But it is hard to say where exactely the error comes from without the contents of your maps file and the related database. You could try if delivery is working when you set (an additional) mailbox map in the ...

This problem can be tackled either by postfix or dovecot. In dovecot, you should set the LMTP service to reply with temporary reject 4XX (for your "special" domain) when postfix send email. In postfix, you need to configure postfix so it must defer the email if the recipient domain match your "special" domain. Option 1 isn't possible because -unlike ...

...I eventually figured out that the file ownership and permissions details have changed. And, I made a small error in the configuration files, too. As many software packages do, the new scheme installs with examples that include many comments and commented out lines that prompt you to get the configuration you want. However, there was no line like this in ...

For received email, you can rely on Delivered-To to identify the correct recipient as @sebix has said in above comment.The challenge is, if the email has more than one Delivered-To header. So you must modify the grep to search user@example.com mailbox grep -r -m 1 '^Delivered-To:' directory/ | grep user@example.com For sent email, you can rely on From ...

Taken from postfixadmin FAQ 1) Why isn't PostfixAdmin creating my mailbox? PostfixAdmin is only a web interface for storing configuration settings. It does not (by default!) have the ability to create mail folders on disk. In a normal setup, sending the 'Welcome' email accomplishes this task - as Courier/Cyrus/etc do it (and have ...

Some workaround for postfix < 2.11 The author suggested that you need combination of reject_sender_login_mismatch and check_sender_access. Parameter reject_sender_login_mismatch will reject if the sender doesn't defined in their permitted username. Looks like you already have query for this in mysql_sender_maps.cf. Parameter check_sender_access will ...
