What's the deal with all these ISPs that set their MTA's to report "Unable to deliver mail for 4 hours"???? I'm getting tired of the errors and want to tell the mail admins at the other end "according tto RFCxxx, the timeout should be set to X". Unfortunately, I don't think there is such an RFC. Four hours seems at least 20 hours short to me. Am I nuts? Let me re-phrase that ... :-) Peter Laws SCAN-L, W5YM-L, UAWEB-L
