Please help a mutt newbie out. I have searched through archives and I am still not able to find the answer to this.
I am using Mutt inside our network to send emails out to the internet. Because it is an internal PC hidden behind a firewall, it does not have a resolvable hostname. This causes problems because many mail system refuse the email if the hostname used in HELO is not resolvable. What can I do to force the HELO generated by mutt to use my outside SMTP hostname?
