    I seem to have problems with Mail that other people don’t have. Some examples:

    - ALT-DELETE not working;
    - Occasional clunky/slow and unreliable application of my mail rules (some disappearing messages);
    - Gmail and iCloud messages not being backed up in Time Machine (but Hotmail is);
    … and most recently…
    - A month-old Gmail message showing in encrypted form, when it wasn’t when I first received it (I can still read it on

    I can only assume there’s some kind of corruption in my mail database, so am considering reinstalling Mail from scratch. Any good advice on doing this, and/or theories as to why I’m getting these problems?

    For information I am using a 2011 Macbook Pro and iMac, and have since kept the OS more or less up to date - now Sierra.

    I don't use gmail, but I recall reading other posts from those who do, that report that (for some reason) seems to have lots of problems with gmail.

    A re-install of Mail (you'd probably have to reinstall the entire system) might help, but then again, might not make a difference at all.

    It might be some setting WITHIN the existing that requires tweaking...
