You need to do this instead: $ openssl s_client -connect mail.myserver.net:587 -starttls smtp The most common SSL-just-stops-working issue is that your certificate expired. Check that by looking for "Not After" in the output of: root@mailserver# openssl x509 -noout -text -in /path/to/server.crt -- Matt Mullins _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
