Hello,
All this seems to be something very different from what postfix and
other smtp usually does. So, may be the problem is with the concept, not
with the implementation.
May I ask you why you need to change the domain name part of the mail
delivery address? Can you provide us with information on your mail
accepting and delivery needs?
May be if you look from a different direction, you can see a different -
and more appropriate - sollution.
I don't think I'm doing something out of the ordinary but that's just me
:-) Here's it goes:
I use unique email addresses (aliases) for every website I register or
where I order something. Right now I have close to 300 aliases using
several different domains (private & business). On my current ancient
CentOS5 mailserver Postfix handles those domains and the aliases. So all
mail is processed by postfix and then delivered to dovecot. The new
mailserver will use Postfix plus some groupware software and the concept
is taken from http://www.postfix.org/VIRTUAL_README.html: Non-Postfix
mailbox store: separate domains, non-UNIX accounts.
So I'm using virtual_mailbox_domains, virtual_maibox_maps,
virtual_alias_maps, virtual_transport and canonical_maps and the
accounts are stored in OpenLDAP.
Examples of how email addresses are handled:
[email protected] is delivered to [email protected] because
[email protected] is an alias of [email protected].
[email protected] is rewritten to [email protected] because it's in
canonical_maps and then delivered to [email protected] because
[email protected] is an alias of [email protected].
The second example is the reason why I asked about canonical_maps with
LDAP that would do @otherdomain.tld -> @mydomain.tld.
In my new test setup this all works fine although I don't doubt that
Victor could find something odd in my setup that requires me to read
many more RFCs to get a clue :-)
Hope this makes sense.
Regards,
Patrick
