We have a client who is unable to send e-mail from their domain exchange server (using Brighthouse as ISP) to any e-mail address at AOL and Yahoo. They can send e-mail to any other address. We are able to send e-mail from their server to our domain e-mail in under 60 seconds.
24 hours after the e-mail has been sent to any AOL or Yahoo address, a message is received back to the sending address stating their e-mail has been delayed. Within a few days, a message comes back stating the e-mail was never received.
This site is able to receive all e-mail from any site including AOL and Yahoo addresses, but they are unable to send to any Yahoo or AOL address.
Does anyone have any ideas? Brighthouse support states everything is fine on their end, Yahoo doesn't seem to have a way to contact support, and AOL will not talk to us unless we provide a member screenname which we do not have.
Thank you in advance for your help.
