[cobalt-users] Mail delivery fails on RaQ2

[Markus Wolff <wolff@xxxxxxx>]

Hi there,

we´ve recently installed a RaQ2 and everything is set up and running
great, but I still have a problem with mail delivery:

There is a user with the account name, let´s say, "USER" who has three
mail-aliases: "User.Name", "info" and "webmaster".

The RaQ2 is set to accept email for that domain, the MX-record has also
been set up and seems to be working.

When I write a Mail to one of the user´s aliases the delivery fails with
the following error message:

info@xxxxxxxxxxxxxx:
  SMTP error from remote mailer after RCPT
  TO:<info@xxxxxxxxxxxxxx>:
  host my.server.de [my.ip.add.ress]:
  550 <info@xxxxxxxxxxxxxx>... User unknown
  
  
Is this a common problem and if so, how can it be solved? Any clues are
appreciated...

Regards,
  Markus
