We receive around 50+ emails from a bank that we work with. Sometimes, their emails are delayed by one day. We are trying to understand the issue and we are trying to fix it. We have put the domain to our whitelist. However, this has not resolved the issue. The header is below:

Although this message appears to have been sent on Friday (July 26th), it was received by our Outlooks on Saturday (July 27th).

We are using a third party webhosting service with managed VPS. Although we have partial access to cpanel and WHM, the configurations we can do are limited.

Any help would be appreciated!

  • Google for "greylisting". – Rob Jul 30 '19 at 12:19
  • @Rob but with greylisting, once authenticity has been established emails won't be grey listed, so I wonder if that is the problem. – Steve Jul 31 '19 at 6:15
