Scan mails from Getmail (Postfix/Dovecot)

[Christian Schrötter]

Hi rspamd-users!

I want to scan all messages received by Getmail. What's the preferred way to achieve this?

Getmail is an IMAP/POP3 fetch client. It can execute external commands to deliver fetched messages, e.g. dovecot/deliver or sendmail.

I could reinject the messages with sendmail to Postfix and include rmilter. But local mails are whitelisted by default and I couldn't use the reject feature anymore. Furthermore SPF/DMARC checks within rspamd would possibly fail.

Any ideas how to solve this?

Regards,

Christian

Rspamd works best on the MX. It could work with downloaded mail but
would require tuning (stuff like SPF may not work correctly & is best
deactivated).

You could use rspamc in LDA mode. Or MTA integration is another fine
possibility (Rmilter works with Sendmail too).

You could set `spamd { whitelist = ; }` in `rmilter.conf.local` to see
that mail from the localhost is scanned. Rspamd disables some checks
(SPF among others) for the localhost, this is fine.

You should *not* reject downloaded mail as you will generate backscatter.

Best,

Just for the record: there is a problem with `spamd { whitelist = ; }`

Sorry, forgot to CC the list...

Thanks for the hint about rspamc LDA mode. Works like a charm. I should have read the fucking manual! :-)
