Hi From time to time I notice on my server that there are lmtpd processes running eating up my processor.I have seen 4 lmtpd's open causing a 4.x load . They seem to run for a very long time (have had a couple running for more than a day and then I decided to kill the process -- with no obvious effects on the mail system...) and I'm never sure if they are doing what they are supposed to, or if they are in a hung state.
What determines the duration and quantity of the lmtpd process? I'm just not sure if I should be worried or if the processes are normal and I just happen to stumble on them during the normal operation of things. When should one be worried, and what can be done to prevent it ( if this is indeed a "strange" thing). Thanks.
