Hello,
I'm currently using two postfix servers. One is the MX server, it does
grey/blacklisting, content filtering, and forward accepted emails to a second
server. The second postfix (lets call it MailGW) does virtual aliasing, and
delivery according to a transport map.
Currently, an email coming from outside for one of our domains, enter MX, is
transferred to MailGW where its recipients addresses are converted (most of the
time) to someth...@mail.univ-lyon2.fr and forwarded via transport map to the
final destination servers.
Soon, our final destination servers will change (to Google App's servers).
During few months, we will have to provide double delivery. Unfortunately,
Google servers will receive emails for the domain "univ-lyon2.fr". So the
virtual aliases map will look like something like that:
public-addr...@univ-lyon2.fr u...@mail.univ-lyon2.fr,
public-addr...@univ-lyon2.fr
some-al...@univ-lyon2.fr u...@mail.univ-lyon2.fr,
public-addr...@univ-lyon2.fr
...
and transport map will look like this:
mail.univ-lyon2.fr smtp:[final destination servers]
univ-lyon2.fr smtp:ASPMX.L.GOOGLE.COM
...
That's not pretty, but it works.
After the period of double delivery is over, we will deliver emails only to
Google servers. So the virtual aliases map is to look like:
public-addr...@univ-lyon2.fr public-addr...@univ-lyon2.fr
some-al...@univ-lyon2.fr public-addr...@univ-lyon2.fr
...
The first line looks pretty silly to me. Is there any way to tell that
addresses not listed in virtual aliases map are to be forwarded "as is" ?
Thanks,
Patrick PRONIEWSKI
