Dear, i have the next problema, my customer, send payments for email to his clients.(email bulk)
But mail queuing grows, although the email, of the same typem, is sending too. I do the capture with MEG but not show deny connecition or other errors.
I wait anyone can help me, thanks.
Elsa Bravo A,
If it is a mass mailer, then normally, queuing is caused by hosts limiting the volume of mail sent at one time. If you see a specific error code in the message search (like 451) you can enable a feature called RapidRetry (http://kc.mcafee.com/agent/index?page=content&id=KB77361)which will retry specific error codes more frequently so the queue empties out faster. If the problem still persists, I would recommend opening an SR with support so they can investigate.
Hope this helps!
