[Dovecot] Shared mailboxes not working with . dot namespace separator - values truncated in SQL

[Frantisek Kucera]

P.P.S. Iwas thinking about this again and it is probably not possible to support this combination: dot separator + shared mailboxes + usernames with dots (including the domain part).

So I suggest update in the wiki:

> n.b. If you have dots "." in your usernames (like `name.surname` or `name at example.com`) it is not possible to use dot as a [[Namespaces|namespace separator]]. Don't forget to use `separator = /` in such cases.
