Howdy --
I'm having trouble posting to some mail list, because my hosting uses
Neomail instead of allow me to create real email address for my domain
i.e:

The virtual email listed at the top of this post is:
trashcan@mustardandrlelish.com but the only "real" email address I
have is mustarda@host3.ipowerweb.com?

What's even more odd, is the email confirming that I want to subscribe
make to "trashcan", along with the "Welcome to" email the my messages
our being blocked?

TIA,
David
