Recipient-Adress user.domain@localhost.localdomain ???


after our problem with courier we replaced the courier pop/imap with the dovecot pop3/imap4-Server.

It runs without problems.

But from the first moment, we have the following problem:

The emails are delivered to "user.domain@localhost.localdomain" or (when we delete $myorigin" in to ""

And in /var/log/

Hi Matthias,

I’m not sure what problem you’re reporting exactly, as the data you’ve given us looks correct. The entries in the log look correct to me, and here’s the reason they look the way they do:

myhostname =

This line says that things delivered locally are going to be delivered to this hostname. So everything that has a local delivery address (mailboxes that are physically on the system, or handled by procmail on the system), will have a last entry with In a Virtualmin setup, you usually have your domain email boxes defined in /etc/postfix/virtual. Each mailbox has a “username@domain.tld local-username” entry. And this causes postfix to relay the mail that is directed to username@domain.tld to (which is the mailbox named local-username on host

Anyway, I guess what I’m getting at is: What is your actual problem? Can users not pickup mail? Does mail bounce? What make you think things aren’t working as they should be?

I could be reading any of this stuff wrong (I’m not postfix expert, by any means)…but I believe this is exactly what you’re supposed to be seeing.

Hi Joe,

sorry that I forgot the most important detail of our problem :wink:

Technically everything works fine (after we replace courier with dovecot).
The mail is delivered correct to the users mbox-file.


When a user receive a email-message, which was sent to a domain hosted on this server, he will see a "to-address" like " in his Email-Client. And not the normal "".

On our other servers (debian, postfix, mysql-virtual) this problem is unknown.

Is there any chance, to avoid this "to-adress".

I’m realy helpless.

Thanks for every advice.
