postfix 3.6-20200316 FreeBSD 11.3 p7 OpenSSL 1.1.1f For several years, I was able to sent mail via Outlook. Suddenly, as of yesterday, it fails.
This is the log output from one attempt from postfix: Apr 8 05:33:46 scorpio postfix/smtp[73032]: Trusted TLS connection established to smtp.office365.com[40.97.124.210]:587: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Apr 8 05:33:46 scorpio postfix/smtp[73032]: 48xzc94xjxz5cMW: SASL authentication failed; cannot authenticate to server smtp.office365.com[40.97.124.210]: invalid parameter supplied I know this is not a postfix problem; however, I was wondering is anyone had any ideas as to what might have suddenly happened. -- Gerard
