Problem with alias/forward to multiple addresses

[pwcr]

Hi,

like the person in this topic: http://www.howtoforge.com/forums/showthread.php?t=34447 I'm trying to create alias/forward which would deliver emails to two local mailboxes.

I tried:
- adding 2 aliases with same source address and different destination addresses
- adding a forward with multiple addresses in destination field, separated by whitespace

Test mails to alias address are not delivered to mailboxes.
Mail log shows no problems.

After I send the test email, a new folder appears in /var/vmail, named like the first destination address, for example testuser@example.com. This doesn't seem right.

The system is Debian Lenny, ISPConfig 3.0.1.3. Mail is setup using this how-to: http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3

Mail server is ISPConfig *slave* server, the web interface is hosted elsewhere. Mail works ok otherwise, even forwards/aliases to one destination email work ok.

Any ideas?

Regards,
Peter

Make sure that the alias address is not the sma ethen the mailbox address.

Alias address in not the same as any of mailbox addresses.
I did some more testing, interesting results.

If I create (in ISPConfig) aliases testusers@domain1.com > testuser@domain1.com and testusers@domain1.com > someuser@domain2.com, the mail sent to testusers@domain1.com is delivered to both mailboxes.

However, if I create aliases testusers@domain1.com > testuser@domain1.com and testusers@domain1.com > someuser@domain1.com, the mail sent to testusers@domain1.com is not delivered to these mailboxes. Instead, the folder /var/vmail/testuser@domain1.com is automatically created, and inside it another folder someuser@domain1.com, and inside that folder the usual "cur" and "new" subfolders.

Apparently there is a problem with 2 aliases with the same name pointing to 2 different mailboxes in same domain.
