Is it definitely the only thing AT&T support? Has David opened a ticket
with them asking why they can't also support the new allocation? ;-)
http://en.wikipedia.org/wiki/SMTPS says
Even in 2013, there are still services that continue to offer the
deprecated SMTPS interface on port 465 in addition to (or instead
of!) the RFC-compliant message submission interface on the port 587
defined by RFC 6409.[6] Service providers that maintain port 465 do
so because[7] older Microsoft applications (including Entourage
v10.0) do not support STARTTLS[8], and thus not the smtp-submission
standard (ESMTPS on port 587). The only way for service providers
to offer those clients an encrypted connection is to maintain port
465.
Cheers, Ralph.
