Hi
Since the Webmin update earlier this month, and only with the sender address “webmin-noreply@ns.domain.com”, I no longer receive emails at the end of the backups.
Here is a log error from /var/log/mail.log:
Oct 9 12:54:48 ns postfix/smtp[2518747]: 55FFD24A0192: to=<micxxxxx@yahoo.fr>, relay=mx-eu.mail.am0.yahoodns.net[188.125.72.73]:25, delay=0.53, delays=0.13/0.01/0.19/0.2, dsn=5.7.9, status=bounced (host mx-eu.mail.am0.yahoodns.net[188.125.72.73] said: 550 5.7.9 This mail has been blocked because the sender is unauthenticated. Yahoo requires all senders to authenticate with either SPF or DKIM. Authentication results: DKIM = FAILURE - SPF ns.xxx.com with ip 51.91.xx.xx = FAILURE.

I sent an email from an account using port 20000, and the email was sent successfully. It’s only through webmin that it’s not visibly sent.
The email was sent to the same Yahoo email address. Result headers:
Received-SPF: pass (domain of xxx.com designates 51.91.xx.xx as permitted sender)
