I managed about 20 lists, most of which are unedited and have moderately large subscriberships. In recent weeks we've twice been deluged with error messages of the type below. I assume that these notes are being distributed because the message in the subject field is not one that listserv is tuned to recognize. Can it be added soon? This particular situation is exacerbated as it seems that the channels are only open sporadically between here and Belfast, so our Belfast user gets innudated with a run of backed up messages, his/her mailbox space is exhausted, and then we are deluged with error replies. Between 12 and 2am today, over 4,000 lines of these error replies were returned to us in 60 to 70 messages. Most had been distributed to the list membership before we happened to notice the situation and popped the list into edited mode. Of course, we shy at the thought of editing 20+ lists. Thanks for your help. Tim Stephen RPI
