Email fails after 3 sends

We are having a strange problem.

Error message 016-781

Sending to the same user from the xerox machine it will successfully send emails 3 times but on the 4th one it fails with the 016-781 error. Then it will email another 3 times then fail again and so on. Our mail server is exchange.


Anyone come accross this issue.

Re: Email fails after 3 sends

Have an exception added in the Exchange server for the account and IP of the printer to whitelist it from being checked by the spam filter.


Look at it from the perspective of the Server.


Someone is sending an email to the same person in quick succession where the subject line, message body, attachment type, file name, footer etc etc are identical, the only thing different from the servers perspective is the size of the attachment.


This is not an issue for a user who sends an email occasionally , but it very much is when sending 3 or more in quick succession (under 5 minutes typically)
