I think you will get the desired results with aliases.

# cat /etc/mail/aliases
user: u...@example.com

Can you post your full configuration? Because it should work
immediately. See:

It's not even necessary to restart smtpd after changes to
/etc/mail/mailname.

I've tried it but it does not solve the problem:
 
 $ mail -v user
 <<< 220 host.example.com ESMTP OpenSMTPD
 >>> EHLO localhost
 <<< 250-host.example.com Hello localhost [local], pleased to meet you

 Nov  1 22:08:35 host smtpd[31333]:  mda event=delivery 
evpid=1dbf7b05c357c219 from= to= 
user=user method=lmtp delay=1m30s result=TempFail stat=Error ("smtpd: RCPT TO 
rejected: 550 5.1.1  User doesn't exist: 
u...@host.example.com")

OpenSMTP accepts the mail. The error message comes from dovecot because
dovecot only knows u...@example.com.

The server is the MX for example.com and host.example.com. Mails for
u...@host.example.com should go to user u...@example.com. Is it possible
to setup a mapping from host.example.com to example.com?

Thanks!
Matthias

Ignore subdomain in lmtp/rcpt-to

[Matthias Teege]

Hello!

I'm deliver my mail with lmtp using the following config line:

  accept from local for local alias  deliver to lmtp 
"/var/dovecot/lmtp" rcpt-to

If I send a message from local the FQDN is added so the mail is send
to u...@host.example.com. Is it possible to ignore the "host." part or
rewrite the address to u...@example.com?

Thanks!
Matthias
