only time it happened. I also commented out the smtp_user and smtp_pass details from mailman.cfg because of the error about the user not existing, just to see if I'll get a different error but I still get the same error, I've uncommented it out though. I'm using port 25 for smtp, I wasn't sure I'll need submission because I'd done that earlier and it didn't seem to change anything, does mailman need submission? > -- > GNU Mailman consultant (installation, migration, customization) > Sirius Open Source https://www.siriusopensource.com/ > Software systems consulting in Europe, North America, and Japan > -- Ibiam Chihurumnaya [email protected] _______________________________________________ Mailman-users mailing list -- [email protected] To unsubscribe send an email to [email protected] https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/ Archived at: https://lists.mailman3.org/archives/list/[email protected]/message/VIQGJZIC3ZLTJLSZNWXLXWA5BY5KP4WX/ This message sent to [email protected]
