kindly elaborate the following statement:
"For maximum compatibility, you need to set both SSL and non-SSL
socket
factories and port numbers and ensure that there is fallback from one
to
the other. SMTP over SSL is port 465, SMTP over plain sockets is port
25
(which is often blocked) or 587 (often not blocked)."
what are the ssl and non-ssl socket factories and port number?
thanks.
