If this is the case, be careful not to end up with two
different instances of the same file when making changes.
Quit, or continue with caution.

If this is the case, use ":recover" or "vim -r /usr/local/msmtp/etc/msmtprc"

If you did this already, delete the swap file "/usr/local/msmtp/etc/.msmtprc.swp"
to avoid this message.

Swap file "/usr/local/msmtp/etc/.msmtprc.swp" already exists!
