[Rspamd-Users] postsrsd and (DKIM signing) rspamd postfix milters together?

[Ronny Seffner]

Hello Franta,

setup here:
- rspamd via rspamd_milter = inet:localhost:11332 and (non_)?smtpd_milters = ${rspamd_milter}
- postsrsd via [sender|recipient]_canonical_maps = ...,tcp:localhost:1000[1|2] (before this, I incude maps with my own and backup_mx domains to disable SRS for these cases [incoming, backup mx])
= it is possible

- DKIM signature includes which header fields were part of signature process, so you can add new header fields (as additional received lines) without breaking signature
- ARC - done by rspamd if you wish - can validate original DKIM and sign new in case of redirection/forwarding, but not all recipient providers supports ARC so far (it will be ignored in worst case)
= no problems with SRS and DKIM (via rspamd) but it (SRS) fixes SPF checks at recipient side - also in case of DMARC (you need SPF pass + header from align OR DKIM pass + header from align)


King regards
