Greetings, all.

This morning, I received notification that a number of major players were removed from the Common Mail Providers greylisting. Providers removed were:

  • Outlook
  • Symantec Messagelabs
  • Microsoft Exchange Online Protection
  • Hotmail
This is a big deal. What was the reason behind this change and where is the sticky announcement announcing this change prior to it happening?

Hi,

Too I received this warnings:

cPanel removed the mail provider “Outlook” from the Common Mail Providers list. Emails received from any IP addresses that are associated with this provider will no longer be exempt from Greylisting.

I received the same message for: Outlook, Hotmail, Symantec Messagelabs and Microsoft Exchange Online Protection.

-Why happened this?.
-This is normal or is a problem/error in our servers?.
-Your recommend me do anything for not have spam problems in my client's accounts?.

Thank you very much. Have a nice day.

Hello,
Same here
I received 5 emails like this one :

cPanel removed the mail provider “Hotmail” from the Common Mail Providers list. Emails received from any IP addresses that are associated with this provider will no longer be exempt from Greylisting.


If you want to continue to trust the IP addresses that are associated with this mail provider, you must add them to the Trusted Hosts list in WHM’s Tweak Settings interface at: https://********************:****/scripts7/greylist/trusted

  • Hotmail
  • Outlook
  • Symantec Messagelabs
  • Microsoft Exchange Online Protection
Any help please ?

I received it, too on a v90.0.3 instance. Not yet seen it on my v88.x instances. I initially locked the instance down and checked for a compromise because the change was not briefed and it happened during a time where nobody with admin access should have made any changes. I can't see any indications of a compromise at first glance. It seems to be an automated / controlled action. Watching this thread though.

Edit: I spoke too soon. One of my v88.0.13 installs also just popped. It seems indeed a controlled action.

Hello,
I'm still investigating about this matter but I think that these providers are putting 90% of emails coming from cpanel in Spam folder so Cpanel did the same with them
The majority of them are Microsoft products as you can see ;)

cpanel doesn't send mail, individual domains do. One would hope that what you're saying isn't the case, because it will immediately affect tons of our users' inbound email. I'd like to hear the official explanation for this.

It does seem odd for cPanel to be taking this action without any announcements.

I hope someone from cPanel's end will chime in and explain their reasoning behind this soon.

Yep. We've had the same message from multiple dedicated and virtual servers. I guess Microsoft are no longer trustworthy enough to avoid greylisting.

I'm getting the same emails now, but also have clients advising they are not able to send emails. I'm currently adding all the IP addresses provided in the emails to the trusted host section, but I would be interested to know why this hasn't been communicated prior to the changes being implemented.

If that is true, it makes perfect sense. And I am 100% backing cPanel's attitude.

I have several customers that rely on cPanel's email, and despite all the email configurations are 100% correct (SPF, DKIM, DMARC, the domains are not blacklisted, they are not sending newsletters, etc), despite all that, all their emails always end up on these providers Spam folders no matter what.

A colleague o mine that works in another company told me last week that he lost a customer just because he couldn't prevent their emails going to Spam.

I would say that this is NOT only a Microsoft's problem, but also Google.

For example, if you have your domain under management in Google Apps for Business, you can ask Google why your emails are going to other customers Gmail's Spam folder.
But if you have not, you cannot.
And if you try to find your way throught the pseudo Google support forums, you end up with solutions like: this happens because your customers have links in their email signature, even if the link is only the website from the same domain. WTF?..

The professional email services of Microsoft and Google are very important to this two companies.
I seriously believe action must be taken from companies like cPanel.
Because this is unfair and a dirty war.

Maybe they are removed from the exclusion list of Greylisting because there is no reason for them to be there in the first place or they were merged into another provider list?
Senders that have valid SPF record, they are excluded from Greylisting by default anyway.

I've opened a ticket to cPanel customer support just to be sure though.

EDIT: While waiting more this post to be approved by a moderator, I got a reply from the cPanel CC with this link:
