Can Blocky handle SRV records via customdns?

[Harnish]

I have a need for some SRV records locally and I have been playing around with getting them into Blocky but I am not having any luck. Anybody have any thoughts?

ChatGPT gave me this to try but it blows up my config:

customDNS:
  customTTL: 1h  # (Optional) Set TTL for custom records
  mapping:
    "_submission._tcp.example.com":
      - type: "SRV"
        value: "10 5 587 mox.example.com"
    "_imap._tcp.example.com":
      - type: "SRV"
        value: "10 5 143 mox.example.com"
    "_imaps._tcp.example.com":
      - type: "SRV"
        value: "10 5 993 mox.example.com"

I would also like to know how to do this or I may need to switch to using a different dns. It also unclear how or if the zone config works.
