You should add a function that allows the attachment of fine lagers to
e-mails.

Now that would be cool

Happy Thanksgiving IMAP!!!

Subject: [Imap-protocol] IMAP capability for maximum APPEND message
size?

I am considering the addition of a trivial new capability to IMAP that
would advertise the maximum size of a message in APPEND (and probably
also CATENATE).  This has the same purpose as the SIZE capability in
SMTP.

Currently, the only message size limit in IMAP is 4294967295 (2^32 - 1)
due to IMAP's use of unsigned 32-bit integers.  Supporting that size is
troublesome due to +1 overflow problems.  Many implementations have much
smaller limits, such as both for administrative and technical reasons
(many filesystems encounter problems after 2^31 - 1).

Rather than have this be a secret, I propose a capability called
MAXAPPENDSIZE=nnn, where nnn is the size.

I considered a somewhat more complex extension might advertise the
server's command line length.  I think that we should stick with RFC
2683 section 3.2.1.5, since a client which is armed with more detail is
much more likely to shoot itself in the foot.

Comments?
