[MlMt] UID server error

[Dave C]

Getting this server error in MailMate on a Yahoo account:

MailMate encountered the following error: “Detected mismatch in UIDs 
received from server (previous value: 105158, new value: 105170).”.
Mailbox: “Trash”.

It’s reporting different folders, none are created by me. I dismiss 
the error and it recurs.

First thought was to delete folder and re-make. Problem is it’s not a 
user-accessible folder.

It started with the latest version update of MM (currently 1.9.7).

What to do?

Thanks,
Dave
