I suggest to update to the latest version 4.74.
[quote]Mercury/32 v4.73 released
Fixes for MercuryI IMAP MercuryI now
saves UID lists any time they change: this should prevent UID
synchronization problems from occurring, but may introduce small extra
processing delays with very large folders. There have also been some
changes in the way the IMAP SEARCH command is handled that should
improve performance and reliability in a number of search scenarios (in
some cases spectacularly), and MercuryI now caches FETCH data which
should significantly improve performance and reduce load when clients
like Apple Mail fetch messages a chunk at a time.[/quote]
