Roger, I use a similar configuration as you describe, multiple devices with only one as a master and doing deletions, in my case after 14 days, and a local mail archive (using Emailchemy to extract mail from Thunderbird and adding it to the archive in RFC format). However, I always use POP, not IMAP, and have only sometimes had the situation you describe and just put up with it and delete previously read emails, one smart mailbox extracting by date and then a bulk deletion. I can only assume the device's data has got corrupted and do not know of any setting that might explain this. As it is only an infrequent happening, I put up with it.
