    I configured my webserver using ansible scripts that are based on the tutorials given here (see
    I managed to get Rspamd working and checked the webinterface.
    In the history I found, that rspamd sometimes rejects fail2ban mails that come from [email protected]<> where <> is my domain.
    It seems that they are rejected because localhost ( was listed in some blacklists DBL_SPAM, URIBL_BLACK.
    It's always another URL which stands next to the symbols.
    But most of the mails from [email protected]<> have "no action" in rspamd...

    Can anyone explain, why this happens?
    Is there a way to fix this (of course I want the fail2ban mails to be delivered)?

    Thanks in advance,

    This happens when the banned IP or domain listed with it is in their lists. You can fix this by whitelisting your address, this can be done in ISPConfig in the mail module.

    @ruppel, is this fail2ban emails from the local mail server host? Ie. smtp connection from localhost or local mail injection via sendmail? Or are these fail2ban emails from another server on your network, and some internal processing there has 127.0.01 in Received:?
