That is incorrect. Port 587 will require SMTP+STARTTLS, not SSL-wrapped SMTP (which is port 465). You'd want to add "-starttls smtp" to your openssl test command.

You should probably check your Internet path with mtr, like: $ mtr --tcp -P 587 -6 smtp.gmail.com (and see how -4 looks as well). It's normal to have hops along the way just be "waiting for reply", and also to see some packet loss (as the "probe" packets used by mtr can be rate-limited), but it should still end with a hop at Google (for me, it's a host with reverse DNS in 1e100.net, which is part of Google's infrastructure). It's possible that one protocol is taking a route through Cogent, who thinks highly of themselves and refuses to peer on IPv6 with some other networks (like Google and Hurricane Electric). -- Chris Adams <li...@cmadams.net> -- _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
