Hi.

I have an weird error here.

If I send a message to a list using an email account that "resides" at
same email server than Mailman, everything works fine.

But if I send a message to a list using a email account from other
server/domain, I receive an error "Recipient address rejected: User
unknown in virtual mailbox table".

For example:

1. I have the list.domain.com hosted at machine/server A
2. I have the domain+account alexander@blah.com hosted at same
   machine/server A
3. I send a message to people@list.domain.com using alexander@blah.com. OK
4. I send a message to people@list.domain.com using other@other.com. ERROR
5. the account other@other.com is ok in Mailman (it's not moderated, etc)

So, seems that if I use alexander@blah.com the request goes by
Mailman, and if not, the request ignores Mailman completely and treat
people@list.domain.com as an ordinary email address.

And, so, seems to be a postfix configuration problem... but... it's
hard to me to figure out where is the problem.

Could someone help me?
