Hi, We often get the following error : X'00B00023' enqueuing mail for delivery when Listserv is trying to deliver mail to a big list (more than 100 subscribers). For each occurence of the error, a xxxx.mail file is stuck in the /var/spool/listserv directory and is requeued when the server is shutdown then restarted. What caused the problem ? And what can we do to prevent or to fix the problem ? Our release is 1.8b, running on AIX, Sendmail 4.03a. A log of the error is attached. Your help is greatly appreciated.
