@ChristineJoieR I am starting to think that you guys are the ones who need to contact an IT Expert, as you clearly have no one there that is. Surely it can not be that hard to understand the issue. We can add IPs to our Whitelists as much as we like,  but that is not going to help OUR CUSTOMERS who are the ones that will still not receive the email.

I am currently looking at other providers who know what they are doing, unfortunately this will be our only fix. Its just unfortunate that the problem is not effecting most of your customer base, as the only way you might care, was if you lost most of YOUR customers.
