People who have no concept of how email works, the pros/cons of the various anti-spam techniques, think that they can install a service but not monitor what is going on (or not going on) have no business running an email server/service. This not only goes for "home" users it also goes for companies. I had one client here in Taiwan where we had installed the internal email system. They used another vendor for their email gateway and installed a Barracuda appliance. One day they called me to complain about delayed emails and insisted that the internal system was to blame. As it turns out they had the Barracuda set to return rejected mails...including those determined to be spam. There were over 100K messages in the outbound queue trying to go to non-existing servers. The system was spending so much time and resources that inbound processing was slowed to a crawl. But since they were sold on the "install and forget" by the Barracuda vendor..... (Don't laugh, but the PHB's first thought was they needed to upgrade the Barracuda to have more CPU/memory/disk.) FWIW, most of the "delayed email" problems I've seen have been due to network problems between the sending and receiving site and neither site had control over it. The delays have lasted for hours in some cases and the uninformed and non-understanding could only conclude that it must be either the sender or the recipient side to blame. -- Fry: Things are different this time.
