I run Postfix to handle my personal mail. I also act as a backup MX host for a friend.
To give him time to return from holiday and fix a broken Postfix installation, I want to keep messages for the backup domains for up to 21 days. However, I want undeliverable messages for other domains to be returned to the sender after 3 days. I've tried this setup of /etc/postfix/main.cf, but it doesn't do what I want. If a message can't be delivered to, say some...@example.com, Postfix will keep trying for 21 days before giving up, and that's a bit long. smtpd_recipient_restrictions = permit_mynetworks permit_mx_backup \ reject_unauth_destination permit_mx_backup_networks = other.com other.org maximal_queue_lifetime = 21d bounce_queue_lifetime = 3d Any suggestions? (It's Posfix 2.5.1) Thanks, Neil. -- Neil Smith http://www.njae.me.uk Milton Keynes Roleplaying Games Club http://www.mk-rpg.org.uk
