we have made the first catch-up-the-release step from stable
Ciphermail 4.6.2 to the latest 4.x version 4.11. After that all
well but we get the following warning all the time:
WARN XFORWARD error code: 550
The only thing we have found in the release notes which might be
related is from version 4.9.1:
"X-Forward-For header is now by default removed unless the IP
comes from a trusted proxy (see /etc/httpd/conf.d/x-forward-
Any idea what Ciphermail actually is complaining about?
The most likely reason for this error is that Postfix does not allow
the XFORWARD for command from the back-end to postfix.
Check whether postfix main config contains the following line:
smtpd_authorized_xforward_hosts = 127.0.0.1/32

we have a custom forward from ciphermail to AV-Scanner. It could be
the problem that the SMTP engine for this product does not support
XFORWARD at all. I will check it.
Do we have a possibility to not use XFORWARD from ciphermail side?
