More good points..
.. for the record, compromises via SMTP are easier to identify, the

Though a bit of a non-standard approach, I collect email subjects and
recipients from accounts that were compromised and used by the attacker
to send email. I use rspamd to mark them, and then I use bash scripts to
check for emails that hit the rspamd triggers and alert via Pushover

Just to be clear because I'm selfish and trying to fix the issue I'm
