I run a VDS server and recently I moved hosts from HostGator to this new server, but several of my clients started having problems delivering email to their own customers. My email queue states only messagelabs as the cause of the undelivered messages. I am having a great deal of trouble with this since my customers can have their email delivered. I have searched on several sites but seems like there's no way to delist an IP address other than being here and having everything setup on my DNS settings. I have created SPF and DKIM correctly and even used Googles DKIM settings for my server, is there a way to finding out what could be causing the blocking by messagelabs?
I am using WHM with CLOUDLINUX 7.2 x86_64
My IP address: 172.93.103.147 and 172.93.103.149
I have checked all RBLs I could find and we're not listed. Hopefully you can help me find out the cause to see if we can make modifications, or if we should look elsewhere for a server. I would very much like to have help from your team or someone reading this.
Thank you.
Here's the detailed information I get:
