[BlueOnyx:24513] Re: Postfix config

[Dirk Estenfeld]

Hello Ernie,

not practicable in real life.
You can't expect hundreds or thousands of mail users to take 587 if their
mail client specifies 25. 
I don't want to have this support hassle.
As an option for manual setting. Fine by me. But not by default. This is too
massive an intervention in the behaviour of the users.

Best regards,
Dirk

One thing I should point out for those people having trouble with helo and
fqdn checks in postfix.

They should only be used on port 25 ie when talking MTA to MTA

Clients should be using the submission port 587 to connect to the BX server,
and that port should not have any helo checks, or fqdn checks enabled
because they have already passed authentication.
