Email Deliverability Tips

Rockforduk
Hello Everyone I really needs some tips on Email Deliverability please, I have everything setup correctly within WHM. I am having major issues with sending email to Yahoo, Gmail and Hotmail. Yahoo is flat out rejecting and all emails are being deferred, Gmail & Hotmail seems to be hit and miss, sometimes it goes into the main inbox and other times it will hit spam box. Really need to find a permanent solution to this as it is impacting all my clients. Thanks Rockforduk

    Hey there! I'm sorry to hear about the issues you're having with the mail deliverability on the system. One of the best resources for this issue is our checklist for spam here, which helps admins setup their server to avoid this: but you may need to speak with Gmail and Hotmail directly if you're continuing to experience this issue.

    Hi CPrex, I have done the checklist when i first setup Cpanel and none of the IP's are blacklisted which is good news. I will have to contact the providers individually by the looks of it is there an easy way to do this? As i can remember i have tried this before and you seem to get the run around via there websites etc. Also how do i view postmaster / root emails please as i know they email you on these as well for verification. Thanks Rockforduk

    There isn't a great way to directly contact any of them, as they usually make you use web forms, and the URLs seem to change a lot. I'm not totally sure what you mean by postmaster emails? If you have an address setup for "postmaster@domain.com" they'd be delivered normally, but there wouldn't be a "root" email address as a catch-all for the entire server.

    Frankly the cPanel default does not work for higher traffic mail servers in regard to Yahoo deferrals. It requires changing a setting that cPanel does not provide any method to change and remain set through updates. However, here's a thread where I discuss and provide the method I used to get around all that and haven't had an issue with Yahoo since.

    @kdean - I read through that thread and there's lots of good info there. Could you get a feature request opened for that? Do you know if there are any implications for mailing lists or other large connection types?
