UIDMode (property)

If true, permanent message identifiers are used instead of the default temporary identifiers.

- (BOOL)UIDMode

- (void)setUIDMode:(BOOL)newUIDMode

Default Value

FALSE

Remarks

This property indicates if a permanent identifier should be used. Normally, the IMAP server uses temporary message identifiers that are valid only during the current session. If UIDMode is true, permanent message identifiers are used instead.

The IMAP protocol operations where UID mode is used are the following: COPY, FETCH, STORE, SEARCH.
