Hi, Theres an example described in the smtpd.conf(5) man page. opensmtpd filters are in ports as a package: opensmtpd-filter-dkimsign The source-code is at: https://imperialat.at/dev/filter-dkimsign/ in main.c It's relatively small and also privilege-separated. It has a parameter to set the domain name (-d). In smtpd.conf you can define multiple filters. See also the man page filter-dkimsign(8) for detailed information. I've replaced dkimproxy (Perl-based and complex) with opensmtpd-filter-dkimsign. It works well for my needs. -- Kind regards, Hiltjo
