On several ocassions I have had an e-mail repeatedly be delivered for 5-7 days. The same e-mail will come through E-Wall, be handed off to ArgoSoft.NET and then be delivered to my e-mail. The last time this ocurred, I followed the trail. E-wall and Paranoid recevied the e-mail correctly and handed it to ArgoSoft.NET. The only thing I can say about the particular e-mail was that it was rather large (32.2 Meg) and that the Argo log kept saying NOOP 250 , NOOP 250, NOOP 250, NOOP 250 ... about 7 times.
What is the source of this repeat receipt? Is Argo not sending a received back to the delivery server? What can be done? I have had this happen 3-4 time over the last year with larger e-mails. I cannot stop the repeated receipt. The sender has a clear outbox.
