Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I've just setup my first virtual mailbox in Postfix. I wonder if it is possible to have two mailboxes on the same server, one virtual and one with shell account, within the same domain?

first@mydomain.com => goes to /home/first/..
second@mydomain.com => goes to /var/spool/mail/virtual/..

What I need is to forward emails using .forward file and it is possible only for shell accounts and not virtual mailboxes. So I need to have both types of mailboxes, one to store and one to forward.

The problem I have is that when I add mydomain.com to mydestination list, no email is saved within virtual mailboxes. And ThunderBird prompts:

An error occurred while sending mail. The mail server responded:  5.1.1 <second@mydomain.com>: Recipient address rejected: User unknown in local recipient table. Please check the message recipient second@mydomain.com and try again.

[UPDATE]

Here's what I've done so far without success:

My /etc/postfix/main.cf:

mydestination = localhost
virtual_mailbox_domains = mydomain.com
virtual_alias_maps = hash:/etc/postfix/valias
virtual_mailbox_base = /var/spool/mail/virtual
virtual_mailbox_maps = hash:/etc/postfix/vmailbox
virtual_minimum_uid = 100
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000

My /etc/postfix/valias:

shell_account shell_account@localhost

My /etc/postfix/vmailbox:

virtual@mydomain.com mydomain.com/virtual/

And then I've run postmap /etc/postfix/valias, postmap /etc/postfix/vmailbox and finally postfix reload. And since I'm using Courier as for IMAP server, userdb -show shows:

virtual

But when I try to send an email to shell_account@mydomain.com, Thunderbird prompts:

An error occurred while sending mail. The mail server responded:  5.1.1 <shell_account@mydomain.com>: Recipient address rejected: User unknown in virtual mailbox table. Please check the message recipient shell_account@mydomain.com and try again.

[UPDATE]

And here's my mail.log:

postfix/smtpd[10098]: connect from localhost[127.0.0.1]
postfix/smtpd[10098]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 550 5.1.1 <shell_account@mydomain.com>: Recipient address rejected: User unknown in virtual mailbox table; from=<mehran@localhost> to=<shell_account@mydomain.com> proto=ESMTP helo=<[127.0.0.1]>
postfix/smtpd[10098]: disconnect from localhost[127.0.0.1]

Yes. Read the docs at postfix.org. –  Jenny D May 11 '14 at 11:58
    
I'm not saying that I've read it completely. But I'm not a foreigner to it either. The problem is that when I put mydomain.com in mydestination, then no email is stored in virtual mailboxes ending with mydomain.com! A pointer to the right direction is greatly appreciated. –  Mehran May 11 '14 at 12:16

Well, I don't know this satisfied your need or not. Suppose

mydestination = local.mydomain.com
virtual_mailbox_domains = mydomain.com

Then add the alias on your virtual_alias_maps

virtual_alias_maps = hash:/etc/postfix/virtual_alias

Content of /etc/postfix/virtual_alias (updated)

second@domain.com second

The idea is generate alias from your virtual_mailbox domains to local domain because .forward only works on local domain.

I found the problem, I needed to write first@mydomain.com first in virtual_alias. Thanks. –  Mehran May 12 '14 at 10:25
