+opensmtpd-filter-dkimsign adds a dkim signature to the email message.
+It supports the rsa and ed25519 signing algorithms.
+
+mandoc is needed only at build time.
+
+It is recommended to run filter-dkimsign as a non root user. For
+example, create a user and group "_dkimsign" (this name has come from
+an example in smtpd.conf(5)):
+
+  groupadd -g 376 _dkimsign
+  useradd -u 376 -g 376 -s /sbin/nologin -M _dkimsign
+
+The private key must be readable by this user.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
