We recently discovered that Domino receives mail also on:firstname.lastname@domain
and
firstname_lastname@domain
even if in GlobalDomain settings it’s not configured.
This is not appreciated by some of our users.
Any idea how to disable this feature?
Many thanx in advance.

Subject: Wrongly formatted address being accepted
Recently we noticed that our Domino smtp servers are accepting messages from our antivirus/antispam system with internet address in the format firstname_lastname.Domino domain@local internet domain (firstname_lastname.Domino domain@abc.com).Now the user mentioned in this address is found in a secondary NAB on the server, the Domino domain is defined as an adjacent one in our primary NAB. The Global domain is defined for address lookup on fullname.
Our server accepts the message by decoding the incoming address to firstname lastname@domino domain and thus deliver the message as the user exists in the secondary NAB. This issue just arose.
At one point I see that as logical since by default if Domino cannot find the internet address for a Notes address, it builds an address of a similar format as the incoming address (firstname_lastname.Domino domain@abc.com) and hence does a reverse process by decoding correctly the this address.
Is there a way to prevent Domino from accepting this kind of address and not to deliver messages?
