I installed spamdyke and now Im seeing a lot of timeouts in my logs. Why?
Badly written software on the remote hosts. It seems a lot of spam software doesn’t handle error codes at all. It just attempts delivery and expects success. When an error code is sent, the software just sits and waits for the success code it wants. Eventually, the connection times out. Sometimes, a remote server will take a long time to begin delivering a large (legitimate) message, which can cause timeouts. qmail enforces a 20 minute idle timeout but it does so silently (no logging). It’s possible you were already getting timeouts and just didn’t know it until spamdyke began logging them. If you suspect legitimate connections are timing out, there are two things you can do. First, you can increase or disable spamdyke’s timeouts. Of course, qmail’s 20 minute idle timeout will still apply but at least you’ll be back where you were before. Second, you can use spamdyke’s full logging feature to log all incoming connections to files. The log files contain timestamps so you can see how qui
