* [Minor] Add HAS_FILE_URL rule for messages containing a file:// URLtwesterhever2024-02-291-0/+7
| | | | | | | | | These are frequently abused for distributing malware via non-HTTP protocols, such as public Samba servers. file:// URLs may also be abused for including files from the victims' machine in a message. Either way, a legitimate usecase is unlikely. Signed-off-by: twesterhever <40121680+twesterhever@users.noreply.github.com>

| * add Betterbird to `user_agent_thunderbird`georglauterbach2023-02-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | See https://github.com/Betterbird/thunderbird-patches/issues/125 for reference. This way, Rspamd will not add `FORGED_MUA_MOZILLA_MAIL_MSGID_UNKNOWN` to mails sent perfectly find with Betterbird. Betterbird (<https://www.betterbird.eu/>) is an adjusted version of Thunderbird, fixing many bugs and adding long-wanted features. It is a common and well-known alternative to Thunderbird, so I think the addition is justified.
