Running Fedora 8, ISPConfig 2.2.32, postfix, dovecot, Coldfusion 8. It is my understanding that you cannot run sendmail and postfix together from reading the post on this forum. All mail accounts will send and receive mail, FormMail will deliver mail to local user. However, other forms that use sendmail 97% of the time will not send out mail. It is my understanding that Postfix will do the same task that sendmail does. Can someone direct me in how I can fix this problem. One last question that may play an important part in this; the primary and secondary dns for the server network, should it be the primary and secondary dns from your ISP? Thank's for your time and patience!
