Anyone ever hear of Message Submission Agent (port 587)?
I don't understand all this whining. There is a service on port 587 for
exactly this situation. It is called the Message Submission Agent port
and almost all modern MTAs support it, even Exchange 2003. We use
this with our remote and travel users and it works great and haven't
had a problem using it with any ISP encountered to date.
Another method that many companies use is VPN or PPTP between
their remote clients and their home server. Not too hard to set up
and it is very secure.
In a perfect world, spam and network abuse would not exist and port 25
blocking would not be necessary. In the real world where AOL estimates
that there is now over 10 million home and business PCs that are infected
with backdoors and trojans (thanks to Windows insecurity), blocking port
25 is not only necessary, but should be required for every ISP. And this
is only the beginning if we are to get a handle on the abuse originating
from these infected PCs. At some point in the future, "consumer grade"
network access will be severely limited to HTTP and a few other standard
ports and protocols.
