I'm using WHMCS and when ever it sends out a email it goes to peoples spam or junk inbox, how do I avoid this? I already switched whmcs to use smtp but that never helped, the most emails I have it set is to 5 every 5 minutes yet I still get flagged for spam?...Anyone know how to avoid this?

Do you have the correct DNS entrys for everything such as rDNS, etc? Have you also checked to see if your IP is listed on any RBL's? Have you added/have an SPF record? Last edited by Server Management; 02-18-2012 at 05:23 PM.

Not really sure to be honest, I checked spamhaus but my IP isn't listed there yet yahoo, gmail and hotmail all discard my emails. How do I make sure I have the right DNS entries and rDNS and how do I add a SPF record? I'm using cPanel.

It would be better you can put spammer mail account into black list he never comes to junk box as well spam

First, you need to make sure your server's hostname is a valid fully qualified domain name, and make sure that the name is a subdomain of that domain, don't use a primary domain as the hostname for your server (for example, use server1.mydomain.com as the hostname, not mydomain.com). You also need to make sure your server's hostname matches the reverse dns for the primary ip of the server. You also need to make sure that the forward dns for the hostname matches the primary ip of the server. It also helps to have an SPF record that is valid that allows your server ip to send mail on behalf of your email domain. It also doesn't hurt to set up domainkeys. Also you'll want to check the most popular blacklists (there are quite a few) and make sure it's not listed there. One in certain is the trendmicro list which I've found has a lot of errors in it that some large mail providers use. Those are some basic things that you can do that will dramatically improve mail delivery.

You have to add SPF and RDNS first. Also have a look at Domain Keys also. SPF can be setup from cpanel using the option "Email Authentication". You can add your mail server IP and save it and then enable SPF option, at the same place you can also enable Domain keys. Also check your IP in other blacklists in anti-abuse.org and your IP reputation in senderbase.org.
