Is it possible to turn off non-deliverable reports per mailbox? For instance, if we don't want any NDRs generated when anyone sends to a specific mailbox but still want NDRs generated for all the other mailboxes.

Hi, As far as I know you can't disable NDR's for a specific mailbox this can only de enabled or disabled per remote domain. But what you can do is make a transport rule which blocks mails/drop silently when mails are send to a specific recipient, maybe this is an option for you. Regards, Johanblog: www.johanveldhuis.nl

Thank you. I hoping to not have to resort to transport rules but I guess it is the only option in this case.

Hi, Ive tried to set up a transport rule for this but since its the exchange server that is sending the message it doesn't seemt to work. I don't want any ndrs to be sent to user1@domain.com and have setup the rule below: Apply rules to messages sent to user1@domain.com and when the from address contains "microsoftexchange" or "microsoft exchange" or "MicrosoftExchange" Delete the message without notifying anyone. /Erik
