Port 587 is for *authenticated* SMTP, as you say. My SMTP uses a different
'quota' system where users don't authenticate, but rather are restricted to
a lowish number of emails per day (and before you say 'open relay', this
system has been proven to be an effective alternative to authentication for
over 10 years). Spammers don't have the incentive to try to guess an actual
member's email address (exim looks at the sender's 'from' email address to
determine if they are allowed to send), and I have never seen anyone
successfully guess a member's email address yet. Trust me - it works, so
let's not discuss that strategy.
Because port 587 is for authenticated SMTP, I do not think I can or should
use it for this.
