As I release mail in 20 message chunks from the 3000 message backlog on the secondary , I'm generating a good bit of backscatter. Is there any easy automatic way to move DSN (delivery service notification) messages into the hold queue on the secondary so I can deal with them at my leasure? Am I explaining the problem clearly enough ?
--Mike Bird I hope there's a clean solution, but if not you could temporarily block outbound SMTP (e.g. with iptables), process the backlog, then use some grep/awk magic to purge the backscatter from the mailq.
Thanks.
I think I have it going.
