Hi,
Searching for Spamdyke TIMEOUTS gets this from Spamdyke:
"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."
Hope it can help.
