Mail Outgoing Server almost ALWAYS offline (ATT internet)
ATT outgoing port is supported to be 995 with SSL. That's what I have set. Incoming port is supposed to be 465, but that's irrelevant here (because mail arrives fine, it's sending that's an issue, and because Mail allows you to specify the outgoing server port, but has no comparable entry for incoming server port anyways).
I can send mail is I use ATT webmail; it's Mail 4.5 that fails. Right-clickng on the ATT server in Mail shows that Mail regards that server as "offline."
Emails I want to send will, as previously stated, eventually go through if I let them sit for an hour in the outbox. That's no good for time-sensitive business, of course, and Apple's glitch with offline outgoing mail servers is quite famous.
Ideas? Fixes?
