It appears that pop.gmail.com *doesn't* provide SSL on port 587.
martin at mira:~/doc$ telnet pop.gmail.com 587
Connected to pop.gmail.com.
Escape character is '^]'.
220 mx.gmail.com ESMTP 13sm5173422wrl
This rather looks like an unencrypted SMTP connection to me. Indeed,
port 587 is the mail submission protocol.
