Hi all. New to the list. I have looked at the RFC and can't seem to
interpret what I need out of the document, so I thought I would ask here.

 

In the APPEND command, it accepts a parenthesized list of flags, which can
include custom flags. My question is, what should the server response be if
the APPEND command includes custom flags, but the server does not have the
ability to store these flags?

 

Thanks in advance!

 

Tom

Timo certainly describes a correct behavior, and probably the most strictly correct behavior.

In my opinion, a more useful behavior is to issue an untagged NO identifying the unknown flags as a warning, but otherwise append the message and just ignore those flags.

RFC 3501 says that keywords are created "by attempting to store those flags in the mailbox".  This is somewhat ambiguous due to the use of lowercase "store", but I interpret this as meaning that only a STORE or UID STORE command can create keywords, and a COPY or APPEND command can not.
