yes, is on the server: that's why I said that the files had the  
consistent name change.
Well, that means that with all its faults Mail.app is not sooo bad!
I checked on another system with many OutLook and Thunderbird clients  
and it looks like they might have lost the flags previous to the  
change. I could write a script to update those files consistently to  
the current dovecot-keywords, when required. This could be an option  
of the migration script, say a --fix switch that would make it look in  
courierimapkeywords and add the keys to dovecot-keywords when they do  
not exist and then update the name of the message files when required.
