Is it time to create an entry in /usr/ports/UIDs and /usr/ports/GIDs for the mail/rspamd/Makefile to use, rather than nobody? This would help with consistency for those that move between sites to manage rspamd easier.
I scanned both for free ID's on either side of redis. This would be a great help, particularly for those like me that use unix sockets. I'm temporarily setting _rspamd:_rspamd to 533 for both ;)

New revision: 494558
Added new user rspamd to be used for mail/rspamd.
Reason for this is, if you like to use rspamd to also sign emails using DKIM, ARC,
rspamd need access to the private key used for signing.
As user nobody is correctly used to run rspamd each service that fallback
to user nobody would have access to the private key, which is a security risk.
New version uses now this user, please see 236505.
I close this one now.
