Supported Standards

The Internet RFC 2086, IMAP4 ACL Extension,

http://www.ietf.org/rfc/rfc2086.txt?number=2086,

is the standard that defines the access control lists (ACLs) used in the IMAP4 protocol. The Message Server has supported RFC2086 since version 5.0.

RFC2086 describes the ACL as a set of identifier and rights pairs. For our purposes, the user ID for the IMAP user is the identifier.

The standard rights defined are:

• l - lookup (mailbox is visible to LIST and LSUB commands)

• r - read (SELECT the mailbox, perform CHECK, FETCH, PARTIAL, SEARCH, COPY from mailbox)

• s - keep seen/unseen information across sessions (STORE SEEN flag)

• w - write (STORE flags other than SEEN and DELETED)

• i - insert (perform DELETED, COPY into mailbox)

• p - post ...
