This morning we experienced an issue with DNS resolvers on our outbound relays which caused 13,964 outbound emails to be delayed on their path to Google/Gmail. This issue may have added anywhere from 30 seconds to 5 minutes in delay. To give you an idea of the scope of this, 68,522 emails were successfully delivered to Google/Gmail without delay during the same time period. So while it was far from every email, it was not insignificant. This has been resolved.
