[Rspamd-Users] Skip FORGED_RECIPIENTS on mail polled by fetchmail

[Achim Lammerts]

Hi,

guess this could be done with user settings, have a look:
https://rspamd.com/doc/configuration/settings.html#settings-structure
There you can disable symbols or reduce the score of a symbol for 
specific users or sender/recipient combinations.

Otherwise, why don't use a multimap whitelist with a pre-filtered 
"accept" for that special cases?
https://rspamd.com/doc/modules/multimap.html#pre-filter-maps

WHITELIST_SENDERS {
     type = "from";
     filter = "email";
     map = "$LOCAL_CONFDIR/local.d/maps.d/senders_whitelist.map";
     description = "Whitelisted senders map";
     symbol = "WHITELIST_SENDERS";
     prefilter = true;
     action = "accept";
     }

or https://rspamd.com/doc/modules/multimap.html#examples:

SENDER_FROM_WHITELIST_USER {
     type = "from";
     filter = "email:user";
     extract_from = "smtp";
     map = "$LOCAL_CONFDIR/local.d/maps.d/senders_whitelist.map";
     action = "accept"; # Prefilter mode
     }

/etc/rspamd/local.d/maps.d/senders_whitelist.map:
some_other at example.net

Kind regards
Achim
