You could create a virtual SMTP server to listen on your required port

I am not sure if Exchange can be configured to listen on 587 in addition
to 25, but it is accepting inbound authenticated connections is what you
meant. 

 

A work around (as long as your Exchange server is properly configured)
is to add an inbound rule to your firewall (you are running a firewall
aren't you) to redirect incoming port 587 traffic on the external
interface to port 25 on the internal destination.

Hello:

 

We have several users who access their Exchange accounts via POP and
SMTP. Recently, several large ISPs have started blocking outbound
traffic that does not use their servers. Is there a way to tell Exchange
2000 to use authenticated outbound connections (e.g., over port 587)?

 

Thanks.
