Is there a "read only mode" in mu4e? I recently had the case to use mu4e to read emails from a system using thunderbird with maildir. I noticed that for example a file called
somemessage.eml was renamed by mu4e to
somemessage.eml:2,S. Then I noticed that thunderbird couldn't read this message anymore.
After renaming it back, thunderbird was able to read it again.
So, is there a way to prevent mu4e to interfer with thunderbird in this case, for example by setting it into a read only mode?
