Hi All, Here is a strange issue, incoming mail for yahoo fails roughly every 10th time. Also this is (reportedly) only happening to yahoo emails, all other email domains come through just fine.
The setup is on ubuntu 10.4 LTS with the standard packages, postfix, clamav, amavis and spamassassin. I have tried many different solutions, TCP_window size is set to 64, 300 smtp process's is the limit, the system is not being overloaded. I also have worked with Sonicwall to make sure that the TCP packets are not getting munged. Any thoughts? Thank you….
