[Borgbackup] Excludes are ignored

[l0f4r0 at tuta.io]

Hi,

I really can't tell but  you should at least quote your exclude patterns like this:
--exclude '/mnt/backup_snapshot/var/mail'

As a last resort, you can try other kinds of patterns like: sh:, re: and pp: (default is fm: for --exclude and --exclude-from) to see if that helps.

Best regards,
