the submission port in my postfix looks enabled already:
but this looks like that 587 is only accepted if the email is authenticated. this is fine for local users, but how do i receive email from external users on port 587?
smtp inet n - n - - smtpd
465 inet n - n - - smtpd
submission inet n - n - - smtpd
currently, i can send outgoing email fine (my relay host uses comcast's port 587 auth), but i would like to get incoming email working.
from the forums, it seems like i'm going down the right path, but i'm missing something.
i know another solution is to use dyndns to reroute port 25 to another port and then accept that, but surely there is another way...
