Hi, I am getting a large number of NDR's in the QUEUE folder. This seems to be causeing a delay in sending valid emails Restarting the SMTP service clears the emails but this is not a valid option for obvious reasons. Is there anything i can do about this? I appreciate that first bounce NDR;s don't do in the bad mail folder but why does this cause an issue with sending of valid emails and what can i do to prevent it happening? Thanks in advance

Hi nettscore, To be able to help you further with this, we need to be able to see a copy of one of the NDR's. NDR's are usually quite helpful, and will explain the reason as to why the email is undeliverable. Cheers!
