We are running Lotus Domino and recently upgraded to latest release (well , almost...)

On of the new options is that if a mail arrive to the mail server (from spamfilter for example, or any outside source), If a user does not exist

in the mail directory, It will simply answer to the sender "550 xxx@dalet.com... No such user" (accroding to SMTP protocol) (And yes, believe it or not, the previous version didnt supported that, it simple accepted all mails and stored them in a db).

 

My problem, is that when Domino answers this to spamfilter,

I get some kind of "answer" from spamfilter to domino:

Intended Recipient: xxxx@xxx.com

Failure Reason: Error transferring to mailserver.GETMARRIEDINCYPRUS.COM; SMTP Protocol Returned a Permanent Error 550 <xxxx@xxx.com>: Recipient address rejected: User unknown in virtual mailbox table

Dead Failure Reason: Router: Null SMTP reverse-path indicates not to issue a delivery status report.

Is there anyway to disable in spamfilter any kind of reply to our domino, when domino will answer it the 550 error?

 

Thanks,

Eran.
