Support Staff Response
Thank you for your reply. After reviewing our logs, we were able to determine that the issue you are experiencing with delays is due to the DNS of the receiving domain having a very large DNS file. Unfortunately, this is an issue that will be experienced with any provider that uses the same type of email system, and we are not able to adjust our configuration to accommodate this. This is an uncommon issue, as most DNS files are not so large, and this issue should also be intermittent. If you are able to contact the domain owner, to request they review their DNS settings, to verify they are configured as desired or if they are able to reduce the size, this would be the only course of action that could resolve this issue. We apologize for any inconvenience.
Please let us know if we can help you in any other way.
