Re: Routing incoming mail to another server

Caution: I am not an expert, just a piece of advice which
is open for discussion. :P

Let me rephrase the situation.
You have 2 servers namely MX1 and MX2.
MX1 is the one who receives all mail and MX2 is the one
with port 25 blocked.

I think...
You may create another SMTP virtual server in MX1 and
set the outgoing port to the port you desired(other then 25).
Then create a SMTP connector to have the new SMTP
virtual server to respond for address space you need.
Then in MX2, you have to set the port of the SMTP virtual
server to the port you need.

Or...
you can have another easier(IMO) workaround(IMO)
without modifying Exchange settings. You may change the
settings in the Firewall and use NAT to translate ports.
Say, create a tranlation rule so that any connections from MX1
to MX2 via port 25 is translated to port 2500. Then in the
firewall of MX2, you add the translation rule so that any
connections from MX1 to MX2 via port 2500 is translated to
25.

If both works, I prefer the later one as I don't want to change
the default settings in Exchange and it's easy to fall back to
original settings.

Comments and discussions are welcomed.

Hi,

I have Exchange 2000 server.

How can I route incoming mail to another SMTP and to another port.

IOW

Our exchange configuration have several domain names. Now there
is one spesific domain name ( let's say routethis.fi ) I want to
route to another SMTP server and to non standard port.

So in DNS records we have

routethis.fi MX 10 mail.ourdomain.com

So all incoming mail to this domain is coming to our server...

I want to route all mail coming to this adress space to their SMTP server
(server.routethis.fi) port 60066?

How can I do this with Exchange?

PS. The problem of course here is that their ISP is blocking port 25
