Yes something like this may work.

But I need to set 'default-directory' to the directory where emacs was
launched. I don't want to set a fixed path.

Actually I'm using mutt as MUA and use emacs as editor inside mutt.
When I compose an email mutt basically does the following to start
emacs:

emacs -nw /tmp/mutt-file -f post-mode

So I'm using "post" mode to compose my email. I could create a post
mode hook to change  'default-directory' value but i don't know how to
specify "the directory where emacs was launched".

I could change mutt's email file path to the current directory but I
would prefer not to and let its temporary directory in /tmp which is
the default configuration.

Thanks
