Hello me,

That sounds terrible, so please follow the following instructions:
1. Boot into a Live USB.
2. On the bootloader, press 1, select "Live CD", username is root, no
password.
3. Mount the filesystem:

zpool import zroot
zfs mount zroot/ROOT/default /mnt
mount -t devfs devfs /mnt/dev
mount -t procfs proc /mnt/proc
chroot /mnt

4. Repair the bootloader which freebsd-update just fucked up:

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

5. Exit and reboot, don't forget to remove the USB drive before your NAS
boots up.
6. ??????
7. PROFIT!

90% of all emails sent on a daily basis are being sent in plain text, and it's super easy to intercept emails as they flow over the internet?
Never send passwords, tokens, personal information, or other volunerable information without proper PGP encryption!

If you're writing your emails unencrypted, please consider sending PGP encrypted emails for security reasons.

Every good email client is able to send encrypted emails.
If yours can't, then you should consider switching to a secure email client, because yours just sucks.

My recommendations are Claws Mail or NeoMutt.
