SELinux denied access requested by dmail. It is not expected that this access is required by dmail and this access may signal an intrusion attempt.

I think that the issue was indeed related to my mounting my old Reiserfs home disk. I copied the contents to a new ext3 partition, then did "touch /.autorelabel; reboot", and the flood of error messages has slowed to a trickle. (I was also missing entries in local-host-names, which probably accounted for a lot of daemon/postmaster mail rattling around).

I still don't 100% understand the above error message, though, or the exact implications of having dmail deliver to a folder that is on a non-selinux-enabled partition or device. I think it is just the "getattr" that fails, not the disk write, so that the mail is still delivered. Maybe it's related to file locking.
