Problems with port 993 (SSL)

Since yesterday I get phone calls from Apple users about port 993 not
working anymore. Some other users don't have problems using port 993.

No problems on port 143 with starttls.

I've tested it myself on Linux, same problem.
Starttls works, but SSL/TLS does not.

I think it has to do with security problems in the SSL-protocol, and
updates in mailclients. Is here someone who knows more?

My mail setup is a bit old (Debian Squeeze), I am testing a new setup at
the moment with Debian Jessie.

With regards,
