5.1. Mailbox Naming
Mailbox names are 7-bit. Client implementations MUST NOT attempt to create 8-bit mailbox names, and SHOULD interpret any 8-bit mailbox names returned by LIST or LSUB as UTF-8. Server implementations SHOULD prohibit the creation of 8-bit mailbox names, and SHOULD NOT return 8-bit mailbox names in LIST or LSUB. See section 5.1.3 for more information on how to represent non-ASCII mailbox names.
Note: 8-bit mailbox names were undefined in earlier versions of this protocol. Some sites used a local 8-bit character set to represent non-ASCII mailbox names. Such usage is not interoperable, and is now formally deprecated.
The case-insensitive mailbox name INBOX is a special name reserved to mean “the primary mailbox for this user on this server”. The interpretation of all other names is implementation-dependent.
In particular, this specification takes no position on case sensitivity in non-INBOX mailbox names. Some server implementations are fully case-sensitive; others preserve case of a newly-created name but otherwise are case-insensitive; and yet others coerce names to a particular case. Client implementations MUST interact with any of these. If a server implementation interprets non-INBOX mailbox names as case-insensitive, it MUST treat names using the international naming convention specially as described in section 5.1.3.
There are certain client considerations when creating a new mailbox name:
- Any character which is one of the atom-specials (see the Formal Syntax) will require that the mailbox name be represented as a quoted string or literal.
- CTL and other non-graphic characters are difficult to represent in a user interface and are best avoided.
- Although the list-wildcard characters (“%” and “*”) are valid in a mailbox name, it is difficult to use such mailbox names with the LIST and LSUB commands due to the conflict with wildcard interpretation.
- Usually, a character (determined by the server implementation) is reserved to delimit levels of hierarchy.
- Two characters, “#” and “&”, have meanings by convention, and should be avoided except when used in that convention.
