dedicated email setup. Email sent from main server only delivered locally.
I have a two server setup with dedicated webserver and mail server.
Mail sent to a hosted client domain from the webserver (e.G. a web form) is delivered via maildrop and not relayed to the destination as I would expect.
It then can be found locally in the vmail directory on the webserver.
Any other mail to other domains coming from the webserver is delivered correctly, just local domains are delivered, well, locally.
I don't understand why, since mail from the outside arrives correctly at the mail server.
Nov 10 10:57:42 webserver postfix/pipe: A30FF308D: to=<firstname.lastname@example.org>, relay=maildrop, delay=0.11, delays=0.05/0.02/0/0.04, dsn=2.0.0, status=sent (delivered via maildrop service)
I'm running IPSConfig 3.0.3 on ubuntu 11.04
I checked mydestination in main.cf which points correctly to the hostname. webserver.domain.com
Any hint where to dig would be appreciated. Where appart from mydestination does ispconfig or postfix think that they are responsible for a domain? The webserver is not configured as mail server at all.
Thanks in advance
