`authclean` cleanup server is used by reinjecting smtpd running on localhost:10025 by default. It runs after filtermail and currently removes `Received` header to avoid leaking IP address. Can as well be used to replace `Subject` lines with `Subject: [...]`. If there are multiple `Subject` lines, all of them should be replaced. This allows us to avoid dealing with localized subjects, including SecureJoin messages `vc-request` and `vg-request` which can have Subject lines like Subject: =?utf-8?q?Nachricht_von_nrn178fi4=40nine=2Etestrun=2Eorg?=
