I had postfix setup to relay all the mail from my desktop to the stoopid office365 server we are forced to use at work. It worked fine on fedora 27. Now, with everything configured identically on fedora 28, postfix can't seem to send out any mail. I don't suppose anyone else has this combo working? I get errors like this when I enable extra debug output for talking to the office365 smtp server: May 6 14:29:05 tomh postfix/smtp[406521]: starting new SASL client May 6 14:29:05 tomh postfix/smtp[406521]: name_mask: noanonymous May 6 14:29:05 tomh postfix/smtp[406521]: smtp_sasl_authenticate: smtp.office365.com[40.97.24.18]:587: SASL mechanisms LOGIN XOAUTH2 May 6 14:29:05 tomh postfix/smtp[406521]: xsasl_cyrus_client_get_user: Tom.Horsley@xxxxxxxxxxxxxxxxx May 6 14:29:05 tomh postfix/qmgr[406467]: warning: private/smtp socket: malformed response Strike a familiar note with anyone? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
