And you learn the lesson of "don't do anything as root that doesn't
need it" and specifically "don't do anything as root with your own
account, it will come back and bite you".

Permission/user mapping between CIFS and Unix is not an exact science. 
I would tend to advise that you don't use a CIFS mount for your home
directory - it's OK if you are using it for remote storage, but not for
anything important.

It would be preferential to use an NFS mount. But that has issues as
well - file locking across NFS is an issue and performance/reliability
depends to a large extent on the server side.  I don't know what the
underlying OS is on the synology NAS, but it would be worth
investigating.

My general advice would be "don't do it". So, why are you wanting to
put your Evo storage on a network filesystem?  If it's purely for
storage, then get yourself a bigger disk! If it's for backup, then I
think the synology boxes can do SMTP & IMAP - use those to manage your
mail, life will be saner!
