Thanks for helping me out on this!

Thunderbird still shows all my folders, but won't show messages for some folders.  There does seem to be some correlation with the number of messages in the folders (larger folders don't display contents).  It just sits there displaying "opening folder" (or something like that) in the lower left status bar.

>>Thunderbird is less than helpful in telling me what's going wrong, but dtmail shows that dovecot is reporting "out of sync" and a couple other errors (UID out of sequence), then closing the connection (for those folders).  This may happen only after Thunderbird has tried to open the folder that I see these errors with dtmail:

log_path's log file (/home/mario/dovecot/log) has this, which might be interesting:

dovecot: Jan 23 07:12:04 Warning: imap(rvvk40): Compressing cache file /var/tmp/mario/dovecot/.Freescale.ATIC.SAM/dovecot.index.cache
dovecot: Jan 23 07:12:04 Warning: imap(rvvk40): Growing pool 'extensions' with: 512
dovecot: Jan 23 07:12:04 Warning: imap(rvvk40): Growing pool 'extensions' with: 512
dovecot: Jan 23 07:12:04 Error: imap(rvvk40): Sending log messages too fast, throttling..
dovecot: Jan 23 07:12:05 Warning: imap(rvvk40): Growing pool 'extensions' with: 512

(Folder .Freescale.ATIC.SAM is one which hangs on displaying contents.)

info_log_path's log file just has this sort of sequence repeated:

dovecot: Jan 23 07:27:04 Info: imap-login: Login: user=<rvvk40>, method=plain, rip=10.213.160.81, lip=172.16.26.151

Hmm.  I don't see any such file!  Can it be recreated, or maybe restored from backup?
