problems with sending mail

[Gustavo Delgado]

hello, I have the following problem with sending emails, it turns out that if you send mail to known domain names such as gmail, hotmail, they are sent correctly, but when you send them to corporate emails they do not arrive, send them to the shipping monitor and say they are the shipment was accepted, when I give in more information it appears to me that this.


I do not know if there is a lack of configuration in the WHM, so that emails can be sent to different domains

It looks like your emails are being accepted by the destination server.

If they don't make it to the destination inbox, they may be subsequently deleted or marked as spam by the destination server or destination device.

You could check to see if your emails have any potential issues with a free test like Email Deliverability Tool - Check Your Deliverability Report - MxToolBox

Remember, there may be nothing wrong with your emails, but the destination server may have badly or mis-configured mail filtering or handling software in place, or even be using some third party mail vetting service that is not performing up to expectations.

HI @Gustavo Delgado

On top of what was suggested by @rpvw you may also want to ensure you have a valid SPF, DKIM, and rDNS on the IP/domains being used to send.
