Ah, I missed that. In that case I don't see maxage very usefull for IMAP
to IMAP sync, because _IMO_ you can't be sure that the INTERNALDATEs
will match between the two IMAP servers.

Hmm, I'll try to return to the log from you and make some sense of it.
But the log is quite incomplete as you grepped it ...

I suspect the ghost messages to be described at FAQ:

Can I copy messages between folders?
Normally, when you copy a message between folders or add a new message to a
folder locally, `OfflineIMAP`_ will just do the right thing. However,
sometimes this can be tricky ― if your IMAP server does not provide the SEARCH
command, or does not return something useful, `OfflineIMAP`_ cannot determine
the new UID of the message. So, in these rare instances, OfflineIMAP will
upload the message to the IMAP server and delete it from your local folder.
Then, on your next sync, the message will be re-downloaded with the proper UID.
`OfflineIMAP`_ makes sure that the message was properly uploaded before
deleting it, so there should be no risk of data loss.
But I might be wrong.
