testing ssl cert on server using a web service. https, imaps and pop3s all check, but smtps yields the message
"we advise you not to submit any confidential or personal data to this website
because a secure connection could not be established with this website."
running postfix
tls logging:
connect from s097.networking4all.com[213.249.64.242]
lost connection after UNKNOWN from s097.networking4all.com[213.249.64.242]
disconnect from s097.networking4all.com[213.249.64.242]
these work correctly:
telnet mydomain.net 587
openssl s_client -starttls smtp -crlf -connect mydomain.net:587
but cannot get email using ssl to log into either 587 or 564 - get same "UNKNOWN" problem. email smtp w/o ssh works fine.
