# Different IMAP clients work in different ways, that's why Dovecot by default
# only caches MessagePart which speeds up most operations. Whenever client
# does something where caching could be used, the field is automatically marked
# to be cached later. For example after FETCH BODY the BODY will be cached
# for all new messages. Normally you should leave this alone, unless you know
# what most of your IMAP clients are. Caching more fields than needed makes
# the index files larger and generate useless I/O.

It seems that this cache optimization which applies to FETCH is not 
applied to SORT. The client said:

000c sort (DATE) US-ASCII ALL 1:10912

and all message files are read.
