Hi, One machine here is locking on sendmail, don't know why. Look: % ps -ax | grep sendmail 178 ?? Ss 0:00.58 sendmail: rejecting connections on port 25: 24 childr 179 ??

They're blocked somewhere. But, where ? And why ? If I run sendmail -q -v by hand, the messages are sucessfully delivered. I don't intend to put sendmail -q in crontab, but would rather know why this is happening. Could somebody help ? This machine has been somewhat recently installed, and is running a -stable from 97.12.08. Older kernel versions also showed this behaviour, and I have other machines with MUCH more email trafic that don't have this problem.
