Hello everyone,
On my Debian 12 server (Plesk 18.0.73, mail service not installed),
I’m using the built-in msmtp integration to send outgoing messages through Office 365 (smtp.office365.com:587).
When I test manually from Debian shell, it works perfectly:
echo "Subject: Test" | msmtp -v [email protected]
However, messages sent *from Plesk itself* (e.g. scheduled tasks) are not delivered.
The /var/log/maillog shows:
my /etc/msmtprc file looks like:
I have already checked the thread Resolved - External SMTP Server Settings but unfortunately it didn’t solve the problem in my case.
The Office 365 account [email protected] has explicit “Send As” permission for [email protected] and this has been tested and verified.
Has anyone managed to make outgoing emails from Plesk itself work with Office 365 via msmtp?
