bincimap uses only maildir ;)
without server sorting i guess sorting might be done by php, but is the
imap server which eats the whole CPU for a while.

how stable is SM-1.5-CVS currently?
are there *really* no weakly optimized parts on SM(1.4)'s mail retriving
which can cause special overhead?

ok.... i'll go and blame bincimap people ;)

bincimap plan to add SORT and threading on their next version (1.3)
