You could hoist the \. to before the (alternates) to save eye-clutter

Pointless parentheses in the regex; only one alternate.

Deprecated use of message= on a warn verb.
Prefer add_header, placed after the condition.

Should work, though.

Looks plausible, depending on where you placed it in your routers.
The redirect_router might be unneeded, if dnslookup is the first
router in the chain anyway.

Can you set up a testcase, and run with debug? Then you will
see the processing sequence.
