Hello, I would like to run OpenSMTPD for two domains, each of which can send and receive messages. Right now, I have it set up for one domain, and use a configuration similar to https://openports.pl/path/mail/opensmtpd-filters/dkimsign for DKIM.
>From my understanding of the DMARC standard, the DKIM signing domain should >match the domain using in From addresses. I see how to extend this configuration to sign for all domains at once, but how would I sign with only the domain that was used in the From address? Thanks for your help.
