Hi,
I have a working dovecot/postfix/sieve configuration:
Ubuntu 8.04 LTS Dovecot 1.2.6 Sieve 0.1.12 Postfix 2.5.1
The server is configured to host multiple domains. All mail delivery, logins and aliases work absolutely perfectly.
There's only one weirdness: the 'From' address in vacation responses.
If a message is sent to user@hosteddomain.com the response comes from user-hosteddomain.com@hostingservername.com
Obviously it's doing what one would expect in that it's taking the username (user-hosteddomain.com) and appending the local host name (hostingservername.com). This isn't great from the perspective of the hosted user, however, who'd much rather their vacation message was sent from their actual email address.
Clearly I can modify this by using a ':from' statement in each relevant sieve file, but I can't rely on users' mail clients to set this (as not all do) and the webmail client in use on the server doesn't set this. I can almost certainly implement some kind of hack using this, but I'd rather not.
So how does sieve determine the from address to use if it's not explicitly set in the sieve script for the user, and how can I direct sieve to determine the address differently, preferably with a central configuration option that will apply to all users regardless of domain.....?
Regards,
Peter.
