Problem sending an email via mutt

I'm trying to send an email using mutt like this:

echo 1.txt | mutt -s Hello -a file.tar.bz2

It's getting no error, but I didn't receive the email. What's the problem?

Assuming that you are using a local smtp server, have you checked the maillog? If that is the case, please post some of the log...

Try launching mutt with debug level 1 with the command: mutt -d 1

I solved my problem this way (the certificate couldn't be saved, and mutt was silently not sending emails).
