Hierarchy separator recommendation?

[Edgaras Lukoševičius]

The dot '.' will work, but I suggest to follow documentation here: 
https://wiki1.dovecot.org/Namespaces,

And it says:

A commonly used separator is '/'. It probably causes the least amount of 
trouble with different IMAP clients

And I already had problems using '.' as a namespace separator.
