I do not use mutt (one of the most unfriendly Unix apps) so I cannot 
comment on what is the problem here. But I would to suggest one thing to 
you for CLI mail : use the port/pkg smtp-cli

Here is a working sample for mail with attachment (bundled into the bash 
shell array att) :

smtp-cli \
	--ipv4 \
	--auth \
	--server="$SMTP" \
	--port=$PORT \
	--user="$fromaddr" \
	--pass="$password" \
	--from="$fromname <$fromaddr>" \
	--to="$sendto" \
	--subject="$subject" \

If this solves your problem, good luck  : - )
