I set up a mailing list for one of my
website hostings on eUKhost. However when I tried to do some admin I couldn't find any password I might have used that would let me in. However I was able to delete the whole mailing list

and start over.
This time instead of creating the list as xxxxx@ my.domain it created it as xxxxx_my.domain@ server1.eukdns.com. Ugh! You can still post messages to the original address but what went wrong?
I tried to create another list with a different name and it was OK.
