https://github.com/linagora/james-project/pull/4168
We still reject the `#` prefix as it is reserved to denote
a namespace. However, the use of # within the name does not lead
to further ambiguities and can be relaxed.
Names containing `#` are allowed by Cyrus, so relaxing this
conditions helps with data migration from Cyrus servers.
https://tools.ietf.org/html/rfc3501#section-5.1 simply discourages the use of
`#` due to conventions but do
not require it to be banned.
```
Two characters, "#" and "&", have meanings by convention, and
should be avoided except when used in that convention.

Benoit Tellier commented on MAILBOX-392:
In IMAP `&` character is escaped (UTF-7) thus there is no restriction to its
usage in mailbox names.
https://github.com/linagora/james-project/pull/3784 relaxed this constraint and
tested escaping.
