Send an email by sendmail


I have been working on RT3.4.2. I finally managed to get it working but
it doesn’t send emails.
I get this error:

[crit]: rt-3.4.2-2-32-3.7.41371180934316@example.comCould not send mail. (/usr/local/rt3/lib/RT/Action/

I’ve read documentation but I don’t really understand how it works.
Do you know anthing that I should take a look to get it working with
