<p class="">Hello,<br class="">
<br class="">
we are developing a library to show last arrived
messages of all threads in a folder with more than 300k
messages.<br class="">
<br class="">
As per the RFC 5256, the IMAP thread command has only
the option to specify the grouping criteria (REFERENCES
vs ORDEREDSUBJECT). So we implemented an algorithm which
gets the full UID SORT ordered by date in reverse order
then gets all thread relations and then post process all
outputs to obtain the final result.<br class="">

<div>It sounds like what you want is REFS threading, which
Dovecot supports, but it didn't make it into official RFC: <a
