Hi Rahul,

Is there any way for you to change the way mutt gets invoked? As it is, in the
way you've specified, mutt runs in batch mode and the behavior you see is "as
designed". What behavior would you like to see? The behavior as one would get
invoking mutt as:

mutt 'mailto:mail at mail.zz?subject=test&body=hello'
?

Kind regards,

Remco
