smtp.ecs would offer an export-grade cipher, which OS X
would refuse to use and then not opt to use something
better. i *think* that's what was happening, none of the
logs are detailed enough to show it well.<br class="">

Now it only offers ciphers which OS X (and everyone else)
are happy with.<br class="">

BTW, I wonder if in hindsight this ties in with Apple fixing the
Logjam issue with its 30th June patch?</div>

Yes, that sounds exactly right.<br>

It is still doing some strange port-swapping negotiation, which
seems odd. Unless it was because Mail.app was trying port 25 (what
you had told it to use), failed to negotiate a non-export-grade
cipher there, and automatically tried 587 as a 2nd attempt, in case
your port number setting was wrong.<br>
<br>
So it *might* be by design, but still worth raising just so as to
check the issue.<br>
