Iglulik spontaneously booted today.
NFS partitions did not properly remount on one mail server, this may result in some spam not being properly filtered and mail that should have gone to spam and/or other folders, instead being placed in your INBOX. I apologize for this inconvenience.
I have modified systemd unit files for postfix to make these mounts a requirement for postfix to start but unfortunately there is no provision to kill postfix if they go away. I may be able to script something if I can find a way to check a mount point without the check itself hanging.
