Comment (by TemptorSent):

 Pretty much every service that logs incoming connections will be hitting
 DNS (unless you explicitly turn it of, leaving just IPs), as does the mail
 server (mandatory), and any thing else that wants to know the name, ip
 address, mail server, dkim keys, or anything else that DNS provides.
 Disabling nslookups in very specific cases where many cache-misses occur
 on a regular basis, but otherwise it just makes sense to use a local fast
 cache. We don't necessarily need to use the system resolver from gitea,
 just point it at a the ip of the local caching server to use for lookups.
