You're getting confused. tcpserver has nothing to do with delivered or undelivered mails. What this log entry is saying is that 7 out of a maximum of 50 concurrent pop sessions are active. You no doubt have a "-c 50" in your tcpserver script for pop. You can conduct a simple experiment to help find out what's going on. Establish lots of pop sessions using telnet, eg: telnet popserver.host.name 110 Wait until you get the banner then background the telnet with ^Z. Keep doing this and watch the pop logs. Can you get more than 7/50 or do the telnets start to fail? If they start to fail before you have 50 of them, show us the error you get back from telnet. Oh, and at the end of the test, don't forget to kill all those telnets. My suspicion is that tcpserver is started with a kernel imposed limit on the number of children it can fork concurrently and that that limit is much less than 50 that you want it to use.
