Not that it's related to your issue...

Since mutt is expecting the body on stdin, why not put something in like 
"Hey, you've got FAX."

This is not conclusive. The Asterisk 'daemon' is a separate process from 
your CLI process (and your shell process spawned from the CLI process). 
They do not 'have to' be executing as the same user. If the Asterisk 
daemon is executing as root, permissions should not be an issue -- unless 
you're doing something weird with /tmp/ and NFS.

If you replace system() with verbose(), does the command you are trying to 
execute look correct? If you 'copy' the command from the Asterisk CLI and 
'paste' it into a shell and execute it using sudo as the the user 
executing the Asterisk daemon, does it work?

Then that should be sufficient.

Sometimes the 'littlest' thing can trip you up. Usually it comes down to 
ownership, permissions, or environment variables.

Not that this is the proper way to figure this out, but this is what I 
would try next in desperation -- after crossing my fingers.

(Cut and paste each line from this email to a shell.)

AUSER=$(ps --no-heading -C asterisk --format user)

FILE=/tmp/faxes/201306191111.tif

MUSER=earohuanca at gmail.com

echo body >/tmp/body

env --ignore sudo -u ${AUSER} /usr/bin/file ${FILE}

env --ignore sudo -u ${AUSER} /usr/bin/mutt -v

env --ignore sudo -u ${AUSER} /usr/bin/mutt -s in-body ${MUSER} </tmp/body

env --ignore sudo -u ${AUSER} /usr/bin/mutt -a /tmp/body -s as-attachment-and-body ${MUSER} </tmp/body

env --ignore sudo -u ${AUSER} /usr/bin/mutt -a ${FILE} -s new-fax ${MUSER} </tmp/body

Good luck :)
