Smtp Forwarding Rules

[benyago]

Hello,
I've setup Xmail with dovecot on Qnap Turbostation. As far as I can judged this, it works well, exept one Problem.
I would have an setup, that allows to filter outgoing messages from imap clients to adequate smtp server, because many ISP don't accept mails from server with a dyndns setup.

For example
User A send a mail to User B who are user of xmail. This mail should be sent via Xmail's built-in smtp server.

Also User A send a mail to User B@ISP.somewhere. This mail should autmatically being forwarded through xmail to User A smtp - server which is part of his Pop3 account at his ISP.

And generally all messages send from Xmail users should be forwarded to smtp-server of an ISP unless otherwised is defined in filter rules.

The hole purpose is to send all mails through xmail regardless from which location (inside-outside the network) they are being sent.

Can someone help me and give me some advise. The manual does not remain this or I don't understand this.

Thanks in advanced

Frank

The only thing you can do is to delegate outgoing mails to certain reciepient domains to another server. This is done in smtpfwd.tab - see manual for details.
