REQ: Add submission/msa to bb-services

[Japheth J.C. Cleaver]

Adding the following section to bb-services in the distribution would be
helpful (to test for port-587 submission on various mail servers)...

=================================
[submission|msa]
   send "mail\r\nquit\r\n"
   expect "220"
   options banner
   port 587
=================================
