> Nested zfs filesystems seem not to be handled properly or possibly not supported any more. This explains my mail gateway also not mounting all filesystems in /home. It was odd that dovecot stopped working.
> The symptom of the problem is zfs mount -a no longer mounts all filesystems. Zfs mount fails saying the filesystem is already mounted. The workaround is to zfs umount each affected zfs dataset by hand and zfs mount it by hand.
> Generally this has screwed up sites that have hundreds (in my case 122) zfs datasets. The work around might be to script testing each mount, unmounting and remounting if necessary.
> I'm being sarcastic about creating an rc script to clean this up. This needs to be backed out and tested properly before being committed. 

Thanks for the feedback, I’ll try to reproduce this on my side.
