I have been using courier for quite a while for 4 incoming mail servers with several thousand mailboxes using authdaemon/authmysql.
I recently upgraded a machine (reinstalled the OS, reinstalled same version of courier as before, with same settings) and with only a new disk subsystem / kernel, I now get this error on the secondary incoming mail servers (they use NFS to mount the mail users' home directories) System error - unable to forward message. Just to be complete, it gives a 5.0.0 error to the sender, as below: > > This is a delivery status notification from mx2.mail.national-net.com, > running the Courier mail server, version 0.42.2. > > The original message was received on Mon, 22 Mar 2004 01:49:09 -0500 > from fed1mtao06.cox.net ([::ffff:68.6.19.125]) > > -------------------------------------------------------------------------- - > > UNDELIVERABLE MAIL > > Your message to the following recipients cannot be delivered: > > <[EMAIL PROTECTED]>: > <<< System error - unable to forward message. > > -------------------------------------------------------------------------- Any help would be much appriciated. Thanks, Roger Ward
