Hello Gnarlymarly,
Thank you a ton for replying so freaking FAST!! Totally appreciated!
Yea man, So that IP "208.180.40.71" I believe to be one of suddenlink' smtp server IP addresses. Although when I ping smtp.suddenlinkmail.com i've gotten the IP 208.180.40.68. I think that they also use the .71..
the user works from home and her email is flagged the most. We have another user that has gotten an email blocked by a customer' smtp server as well; If you would like I could provide that one as well.
As for the user with the most issues, The problem is that they possibly have a virus? I believe their windows laptop stopped working so she started using a Mac.
From what I am uderstanding, attempt to send another email after 22 hours and it might be delisted? I appologize for a ton of questions for a new account with only (2) posts. This issue has been a problem of our for quite some time now. (3-6 mo) I have attempted to call suddenlink' business support and all they have managed to tell me after 4-7 calls is to forward the email to "spam@suddenlink.net" which ended as a return error invalid user. Again - thank you for your support!
