I started running short on disk space for the non-production FreshPorts hosts. This time, I have decided to ask for donations. See my recent blog post which points to my Patreon account.

Description:
This filter adds a DKIM signature to emails sent through OpenSMTPd. The rsa and ed25519 signing algorithms are supported, as well as the simple and relaxed canonicalization algorithms. The filter can sign emails for several domains, selecting them according to the from-header, but can only use a single selector, managing multiple selectors must be done at the OpenSMTPd level. It depends on the libopensmtpd port. An example of a minimal configuration for signing outgoing emails for domain "example.com" and selector "_selector" would be: filter "dkimsign" proc-exec "filter-dkimsign -d example.com -s _selector \ -k /usr/local/etc/smtpd/dkim/private.key" user _smtpd group _smtpd And then you can apply that filter to the mail that needs to be signed: listen on lo0 filter dkimsign

mail/opensmtpd-filter-dkimsign: DKIM filter for OpenSMTPd

This filter adds a DKIM signature to emails sent through OpenSMTPd.
The rsa and ed25519 signing algorithms are supported, as well as the
simple and relaxed canonicalization algorithms.

The filter can sign emails for several domains, selecting them
according to the from-header, but can only use a single selector,
managing multiple selectors must be done at the OpenSMTPd level.

It depends on the libopensmtpd port.

An example of a minimal configuration for signing outgoing emails for
domain "example.com" and selector "_selector" would be:

filter "dkimsign" proc-exec "filter-dkimsign -d example.com -s _selector \
    -k /usr/local/etc/smtpd/dkim/private.key" user _smtpd group _smtpd

And then you can apply that filter to the mail that needs to be signed:

listen on lo0 filter dkimsign
