@[email protected] would adding those txt records cause any issue to a wildcard redirect I use for myself?

I have xxxxx.com and an auto redirect by my dns provider so that anything sent to [email protected] is forwarded to [email protected] so when I give out the address I can see if it's been shared.

I like the idea of protecting against unauthorized use but wouldn't want to lose my throwaway capability.

I find email servers to be akin to dark arts so am at a loss here tbh.

@[email protected] ok - I'll try it on a less critical domain first, thank you.

I run most of my own services from here to avoid any cloud usage but the one thing I do not dare to host is email - I can't see any refinement in configuration/management has happened since the '70s :-)
