I have a problem with postfix that I can´t send by outlook 365, I can download the emails by pop/imap but not send.
All the other tools I tested worked, google smtp, thunderbird, applemail … But not outlook, this is taking my sleep.
Does anyone know a solution?

Thanks! It is working! This issue occur me a headache a long time ago…
The biggest question: if we are talking about SMTP (postfix), why Dovecot bring the solution?
Hello,
As described in this answer here I would recommend checking your logs for more information.
Run this command:
tail -f /var/log/mail.err /var/log/mail.log /var/log/dovecot.log /var/log/spamassassin/spamd.log
And then try to authenticate via Outlook and try to send an email. This should populate the logs and the information would give you a good starting point for further troubleshooting.
Let me know how it goes! Regards, Bobby
