Comment 2 for bug 1845923

Well, I don't know the exact reason why you implemented the checks. Without the checks the plain and usually consice error message from msmtp was written to the queue folder. After updating the scripts it took me quite a while to figure out what's going on, because of the generic error message ("Failed to create .msmtp file"). Therefore I'm not sure it makes sense to implement checks for all of the command line options of msmtp, there are so many of them. Maybe it would be easier to just pass the error messages from msmtp and skip the checks.
