Re: Problem with aliases - SOLVED

Hi Ed 

I cannot add an entry
[email protected]              test
into virtual table cause it creates loop
It's better and easier to use check_recipent_access  ( postfix feature )
that it rejects every mail from outside directed to [email protected],
[email protected]. Allowed address is only [email protected]

Thanks

BR

As I said in my first message - I can't remember exactly why.  If you
search the archives, I am sure there will be an explanation...

Did you add an entry in virtusertable for [email protected]?

I might try:
[email protected]              test
just to see if that fixes it....

But that' s just me.  Someone else who knows more about postfix and
majordomo might know better...
