Cool Mailsnake
Hi there,

I love those howtos!! :)
True story, I successfully integrated on my productive system. Sadly without the antispam stuff because of performance.

Now I have a different setup with an Exchange 2003 Server. The setup is like this:

WAN -> Mailserver (Postfix without AV/AS)
WAN -> Mailserver (Exchange, different Domain)

I integrated another machine ...

WAN -> Mailserver (Postfix without AV/AS)
WAN -> Mailserver (Postfix with AV/AS) -> Exchange

On that Postfix with AV/AS I have also fetchmail like in

What I want:
WAN -> Mailserver (Postfix without AV/AS) -> Mailserver (Fetchmail && Postfix with AV/AS) -> Exchange
All the Mails from that other domain (this without the AV/AS) land in those Exchange Mailboxes anyway by POP3 but without beeing scanned and moved trough a Spamsnake...

I this possible? Currently I have the problem, that I can't map those users for the fetchmail accounts to the exchange ones (by email address). -> POP3 -> Scan -> Move to Postfix -> == -> SMTP to Exchange -> Deliver

I don't just want to forward those mails from domainA to domainB :-\

I really hope someone could help me get this thing startet!
Just tell me what loglines you need, I look into this forums a couple of times a day.

Maybe it's possible to do this with Postfix transports?
Take a look at

man 5 transport

Hi Falko,

ah allright, I'll dig deeper into that! Thanks for the hint!
I remember something about those transport-stuff mapped to the db-fields, aah I'll just look and take some time.

I'll be back with more questions hehe ...
