Hi,
New as I am to postfix, I have been trying to find some answer to my
current dilemma...
Incoming mails to the domain(s) hit postfix MTA's with antivirus and
anti-spam
these send emails on to a mail storage, today an old iPlanet server
(clustered)
All users, aliases and other user data are stored in LDAP, as per the
iPlanet model.
The user base is updated daily.
Now hey want another server, not iPlanet or JES, most probably a linux/
postfix one
to shadow the main server, getting a copy for every mail going to the
iPlanet server
to also go to the new server, making it a possible replacement system
for the original
one in case of catastrophic failure of it.
I have been looking at the options like always_bcc and the likes, and
although the
recipient_bcc_maps looks usable, it would mean maintaining a huge list
which will
change a lot.
is it possible to just make postfix edge MTA just send every mail it
sends on to the old
mailserver also sent to the new mailserver, regardless of what user it
is? Valid users
are checked already at the edge MTA anyway.
i.e.
Sending Host
|
|
|
Edge MTA with AntiSPAM/AntiVirus (gateway?)
|\
| \__ new Mailserver (new.example.com)
\
\__ old MailServer (old.example.com)
Both servers being configured to receive mail for the same domains and
storing
the mails in whatever fashion that product uses. Both using the same
LDAP authentication
data, but only the old one doing forwards and vacations and such...
(for now)
I know this is a strange way to do things, but this is what this
customer wants at this time
so I am checking if it is even possible to do it without getting in to
more administrative work
then need be, maintaining a recipient_bcc_maps that is up to par seems
like a bit to much
work to me.
it would have been great if one could just have listed two relays to
the domain and gotten
it to send a copy to each one.
i.e. /etc/postfix/transport
example.com smtp:[old.example.com], [new.example.com]
or something similiar...
Anyone has any insight to as how this might be accomplished?
