Topic: Mail Relay through ISP
Hello everyone, I have setup and configured iRedMail 0.6.0 and have everything working except email sending. I need to send my external email through my ISP (Comcast). I have searched the forums and online for any help. I have found a few guides (http://justatheory.com/computers/mail/p … mcast.html), but nothing has been able to allow me to send an email to a gmail account or other external accounts. I will get "550 5.1.0 Authentication required" every time even though everything appears to be configured properly. Any help would be appreciated. Thanks.
