Hi there, Several of our local lists have recently started bouncing messages from userid's like: [log in to unmask] The stated reason is usually "mail origin seems to be a mailer or mail-daemon." This is the header of one offending posting: >Date: Tue, 6 Aug 1991 16:52 EDT >Original_From: NEIS::ALERT >Comments: This is gatewayed mail. Warning: Mail may not > necessarily be returnable through this path. >From: General Delivery <POSTMASTER@USGSRESV> >To: SEISM-L@BINGVMB >Original_To: ISDRES::BITNET%"SEISM-L@BINGVMB" A copy of the entire bounce is below. The NODES INFO1 table shows USGSRESV to be a VAX/VMS machine belonging to the US Geological Survey. I telnetted to sri-nic.arpa and did a quick whois on both USGSRESV and US Geological Survey with no result. I sent to NetServ@PUCC for the Nodentry for USGSRESV and found the name of their techinfo person and netop to be J Fisher (JFISHER@USGSRESV). I debated writing this person, but decided not to when other lists started getting ill w/ the same problem. Some gateways (only on VAX/VMS machines so far) make outgoing mail appear to listserv to be from the userid POSTMASTER. I assume the problem is caused by a recent change to listserv which sniffs out messages that looks like bounces. A good change, by the way, no critisism intended. Having said all that, where do I go from here? Is there some quick, easy fix for this or must it be dealt with on a case by case basis?
