What do you do then if server advertises CATENATE but not BINARY?

Anyway for the other possibilities Dovecot could:

a) Put all CATENATEd messages through the istream-binary-converter, but
just not do any actual C-T-E:binary conversion until the first ~{binary}
part is found.

b) Just treat ~{n} exactly the same as ~{n}, unless it's the first part
of CATENATE.

Maybe this should be aked about in IMAP mailing list .. (Didn't I
already ask something about CATENATE+BINARY combination?)
