When I installed build 13080, I had a few people complain of SMTP
timeouts when sending mail. I also saw a timeout or two on my own mail
client when sending mail, but it was very intermittent, so I didn't
think anything of it.

I installed build 13081 today, and everything seemed fine. At around 4
pm today, out of the blue, ASSP started dropping SSL connections on port
465. Submission ports 587 and 25 worked just fine.

Establishing a connection to ASSP on port 465 worked (the connection was
accepted), but as soon as the SSL negotiation started, ASSP dropped the
connection. This is obviously what was happening yesterday on build
13080 as well, as the error displayed was exactly the same.

When this occurs, NOTHING is logged in the ASSP log. There is no
indication whatsoever that a connection was attempted.

I did some testing - I did a telnet to port 465. The connection was
accepted, but nothing was logged. As soon as I typed a single character,
ASSP dropped the connection.

I tried stopping and restarting ASSP, it still did not accept any SSL
submissions. I tried reverting to build 13080, this did not fix it. I
thought perhaps there was something going on with OpenSSL, so I rebooted
the server entirely. Once the server came up, it accepted an SSL
connection and I was able to send a message, three times. The fourth
time, it dropped the connection again, and at that point would drop
every attempted SSL connection.

I reverted to build 13056, and the problems have disappeared - I see
lots of messages being submitted via SSL once more.

So it would appear something has broken SSL in the new builds, at least
on my server?
