rewrite recipients after /etc/aliases is processed

[Hanspeter Kunz]

Hi all,

I'm trying to figure out how I can deliver mail

usern...@examplehost.example.com

to a central mail server (smtp.example.com) without setting

myorigin = $mydomain

on the example host, because I would like to see where the mail
originiated or was originally sent to in the sender address.

I tried to use recipient canonical maps

@examplehost.example.com @example.com

but then /etc/aliases is not used e.g. to forward email.

I there a way, to rewrite recipient adresses *after* /etc/aliases has
been processed?

many thanks,
Hp

well, my intention was to use /etc/aliases for forwarding mail adresses
like root, webmaster, logcheck, etc. to real users. This would be
different users on every host. That's why I want first to
process /etc/aliases and then route the mail to our central mail server.

any idea how I could do such a thing?

or can I do a host-based mail-forwarding on the central server, i.e.
forwarding mail for root to different sets of users, depending on which
host sent the mail?

many thanks,
Hp.

sure.

thanks for your inputs (also to mouss).

For the record, I decided to do it the other way round:
* mail is delivered locally (so that /etc/aliases is processed)
* an additional ldap-aliases-table reroutes mails for "real" users to
the central mail server.

thanks again,
Hp.
