New set up. EFA on one physical server with three cores assigned. Exchange 2013 Hyper-V guest on different physical server. Three Domains being managed by EFA.

Since yesterday, some Emails showing as delivered in EFA are not arriving at our Exchange Server. Most mail for 3 Domains are being delivered OK and EFA is doing a wonderful job of blocking SPAM but since yesterday the number of emails not being delivered to the Exchange Server is causing concern.

Have gone in and released the emails even though they are not showing as being blocked but still no delivery to the recipients. Does not seem to have any discernible pattern.

Checked the Exchange logs.

Did you create and allow an explicit receive connector for EFA within Exchange? That should be the preferred method.

No. Will try this. Thanks.

Thanks for your help. Receive connector was not required. Exchange Antispam needed to be tweaked.

All good now.
