When using PostSRSd via milter along with other milters (DKIM, DMARC, RSpamd, etc...), should it be placed at the beginning (to be executed first) or at the end (to be executed last)? |

PostSRSd transforms incoming emails and makes them appear as if they originated locally, at least for the sake of DMARC validation. Therefore, you should probably run anything that filters unwanted mails (e.g., rspamd, RBL lookups, DKIM/DMARC/SPF validator) before PostSRSd, and anything that adds signatures or might break if the sender or a recipient is changed (e.g., DKIM signer) after PostSRSd. |
