I've been using Hotmail/Outlook for my e-mail notifications in OMV for years, and they recently stopped working on my NAS. I'm fairly certain that it's because Microsoft has disabled basic authentication which means that even "app passwords" no longer work (yes, I tried a new app password). The log entry looks like this:
postfix/smtp[571250]: 270E81C40798: to=<intentionallyremoved@hotmail.com>, orig_to=<root>, relay=smtp-mail.outlook.com[40.97.212.6]:587, delay=243829, delays=243818/0.1/11/0, dsn=4.7.139, status=deferred (SASL authentication failed; server smtp-mail.outlook.com[40.97.212.6] said: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled.
I believe that Google has also disabled basic authentication for Gmail accounts. Is there any way to get the OMV notifications to work with OAuth? Is there some other solution other than using an e-mail provider with weak security?
Thanks.
