Thanks Consus! By the way (for the list), I neglected to mention the extensions are enabled by the config vars $imap_condstore and $imap_qresync, which default unset. For CONDSTORE, Mutt is only using the FETCH CHANGEDSINCE extension, not the conditional store or other features. On servers which don't include MODSEQ in the initial UID FETCH (where it is not required), this can result in a slight speedup due to the flags not being included. QRESYNC can result in a larger speedup because it can completely skip the initial UID FETCH. -- Kevin J. McCarthy GPG Fingerprint: 8975 A9B3 3AA3 7910 385C 5308 ADEF 7684 8031 6BDA
