Thanks all for kind answers

Actually I now that the problem IS Lotus Domino Server, Lotus Domino is
ALWAYS a problem (I am working on it since 6 years ago)

Outlook express client configured with that imap server took about 5
minutes to syncronize folders (same as squirrelmail)

I know it is impossible to ask IBM for anything.

But the point is another: I don't understand why squirrelmail should
retrieve all the messages in a folder before presenting 15 of them !

could it be a configuration issue ?

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)
