Q: IMAP does not work anymore since upgrade to 10.10.4 and iOS 8.4

Hello,

I can't receive IMAP mail since upgrading tho OS of my Mac to 10.10.4 and on my iPad since upgrade to iOS 8.4. Mail still works on former versions of both OSs. I have already tried to delete and create the Mail account anew (at least on Mac OS), but it didn't work.

Does anybody have similar experiences?

Note: Until now I used STARTTLS method for IMAP, but also SSL on 993 isn't working.

Thanks in advance!

Regards,

Jens

I've debugged the connection between Apple Mail and the server (which is my own BTW), and found out that Apple Mail closes the TCP connection during SSL/TLS handshake. This is clearly a client issue.
Obviously Apple Mail cannot initiate a SSL connection anymore (at least under some circumstances). And yes, I have repaired the permissions ...
