issue2551186 - replace socket.sslerror in mailgw.py. roundup/mailgw.py: replaced socket.sslerror with anypy/ssl_.SSLError also looks like a socket.sslerror was removed from pops handling. added it back using method above. roundupanypy/ssl_.py: defines replacement SSLError suitable for python2 or 3 tested by running nc -lp 995 or 993 (pop3s/imaps) and sending gibberish when mailgw connects. This generates a bad version number SSLError. I need to get my imap and pop mock servers included for testing at some point, but I am not sure how to make them bind to the right port as they are priv ports.
