Yeah, port 25 is the sendmail port.  However, any decent sysadmin can 
trace you through the headers.  A nice thing to do is to telnet into a VM 
system via port 25 and issue a fake domain during HELO.  VM takes anything 
you give it...most modern UNIX sendmails will grab your address anyway and 
stick it in the header...
