[IMail Forum] Solving AOL Wierdness and other problems RESOLVED !!!

[Joe Scharbrough]

Like many in this forum I have experienced the much discussed AOL Problem; Mail goes through ok sometimes and at other times all mail to AOL and some others is returned with the error user unknown. After monitoring this and watching mail go through the logs fine for several hours and then without warning AOL fails for an hour or two and then for no reason it works again I was very frustrated.   We process approximately 150,000 pieces of mail each day and can have 100’s of bounce AOL mail each day. After applying the fix I have experienced NO bounced AOL mail for the last 3 days.   The Fix: Get a SERVER grade 3 Com Network Interface Card for your DNS Server. This card runs about $100 and after placing this card on our Main DNS Server all the problems went away. We had a 3 Com card on that server but not a SERVER grade card. This made all the difference. The card we used is 3COM 3CR990SVR97.   If you try this and it works let me know.
