Hi Stefano,

Thanks for taking the time to reply.

I apologize for the confusion, but I meant that I did not 
experience this problem when I tested it with Thunderbird 
configured to use GMail's IMAP servers directly. I too use mutt, 
yet I always experience this issue regardless the MUA I use.


I schedule offlineimap as a cron job that runs every 10 minutes. 
Here is an example scenario:

13:00 - Offlineimap performs a sync
13:02 - I read email 1234 (obviously I am just making up an id)
13:03 - I finish reading email 1234, mark it as read, and save it
        to a folder.
13:10 - Offlineimap performs a sync
13:11 - Log into GMail and find email 1234 where I saved it, and
        it shows up as Not Read.


I have tried modifying my behaviour so that the above looks like 
this:

13:00 - Offlineimap performs a sync
13:02 - I read email 1234 (obviously I am just making up an id)
13:03 - I finish reading email 1234, mark it as read.
13:10 - Offlineimap performs a sync
13:11 - Save email 1234 to a folder.
13:12 - Log into GMail and find email 1234 where I saved it, and
        it shows up as Read.

As long as I let offlineimap perform a sync before I move the 
email, the change to the status will be retained. Unfortunately, 
that leads to a pile of email that I forgot to go back and move.
