No matter which port I use, 25 or 587, UrBackup gets “login denied (ec=67)” error. Quick check in server logs tells me that it fails on STARTTLS, stating that it’s not implemented. Shouldn’t this use PLAIN or am I misunderstanding this? I did not tick “Send mails only with SSL/TLS” box.
Both ports reachable through telnet.
Using postfix on CentOS
Ok, after playing around with my setup, I can say that this is either fully or partially on me. Server does not return anything useful via ehlo command so either the default behavior after that is to present STARTTLS or that’s what uroni/whoever programmed that part chose. Either way, my bad.
If anyone is interested in the solution - just don’t put in any username and password combo in the settings. Would want to hear a lecture or this, but I’ll mark it as fixed.
Yeah STARTLS was a red herring, because it simply always tries that and fails only if you set it to require SSL/TLS.
Uroni, is it normal behavior to send mail with X-Original-To instead of To: field filled?
