I installed e-smith in dec. ver 4.01 and used dyndns.org and granitecaynon for dynamic dns. I could send and received email. something happened with granitecaynon and my server could not be found. I changed to zoneedit.com and the server is working and I can receive email but can not send email.
My MX record is mail.mydomain.com to mydomain.com
and the cname
e-smith.mydomain to mydomain.dyndns.org
mail.e-smith.mydomain to mydomain.dyndns.org
etc.
any idea why I can not send email
