Sendmail binding to port 587
Last modified: 2007-04-18 12:29:56 EDT
Sendmail by default has been configured to use MSA bindings on port 587,
since about 99% of all people have no idea what MSA is yet this should
probably be turned off as the protocol is still young and more than likely
vunerable to DOS's..
