+ The <systemitem role="package">fail2ban</systemitem> package can
+ be configured to send out e-mail notifications. It does that
+ using <command>mail</command>, which is provided by multiple
+ packages in Debian. A security update (needed on systems that
+ use <command>mail</command> from <systemitem
+ role="package">mailutils</systemitem>) just before the release
+ of bullseye broke this functionality for systems that have
+ <command>mail</command> provided by <systemitem
+ role="package">bsd-mailx</systemitem>. Users of
+ <systemitem>fail2ban</systemitem> in combination with
+ <systemitem>bsd-mailx</systemitem> that wish
+ <systemitem>fail2ban</systemitem> to send out e-mail, should
+ either switch to a different provide for <command>mail</command>
+ or manually unapply <ulink
