Hi Noel,
I'll explain better my problem:
I've this mailserver under a slow dial-up connection.
To fetch email from the main mailserver I use some Perl scripts, and
they are working fine.
I use postfix to queue the emails that needs to be send and then with
the command "postqueue -i" I'll send the emails that I want(they will
be relayed with smtp to the correspondent smtp server).
In this mailserver I'll have most of the emails with a @mydomain.com,
but also few emails with @gmail.com or @hotmail.com
So if I add in mail_users the email u...@gmail.com and so in
mail_domains the gmail.com, everytime that from this mailserver I'll
send an email to any @gmail.com email, postfix think that it's an
internal email and try to delivery it as virtual(Recipient address
rejected: User unknown in virtual mailbox table).
To say to postfix which smtp server is related with the email, I've
used sender_dependent_relayhost_maps.
So the only issue that I've is just how to say to postfix which email
is an internal one, based on the full email address and not based on
just the domain.
So I think that the alias in not helping me (but if I'm wrong please
let me know :) ).
Anyway, this is the output of postconf -n:
