> What do other list owners/ LISTSERV postmasters do in handling rejection > mail? If it's for my low-volume list, I let it go for a day or two before doing anything. If it's for my high-volume list, I immediately set NOMAIL for the offending address. After setting NOMAIL, I send a message to the subscriber (who usually doesn't get it because it also bounces) with a copy to the postmaster at that site (who also doesn't always get it since the problem is sometimes with the site rather than with the individual user's address). The list regulars know that if their mail from the list suddenly ceases, they should send the 'query' command to check their status. On a list that sometimes exceeds 200 messages a day (but usually is 80-100), there's no way I can do anything except send a prompt NOMAIL command. --Natalie ([log in to unmask])
