SMTP spoofing ?

  • From: John R Levine

Are there any routers currently available that can do port 25 spoofing for
dialup users?  That is, when the user attempts to connect to port 25
anywhere, he in fact connects to port 25 on your own SMTP server instead. 

In case it's not obvious, it's for spam management.
