DNS servers for a mail server

strarsis

There are quite secure mail servers that also Let’s Encrypt uses. Should the mail server use these extra secure, up-to-date DNS servers for its own look-ups or would this incur performance issues?

bump There are the DNS servers that Let’s Encrypt uses for example (extra secure and up-to-date ones), then there is Google DNS and Public DNS. I guess due to performance reasons the mailcow DNS part is a caching/stub resolver, so the choice of DNS server is important?

Well, there is only one answer in this discussion, me, bumping it.
Maybe change this automated message a bit, as it feels a bit passive-aggressive and confuses. 🙆‍♂️
