Below is a sample of an address this user could email two days ago but as of yesterday gets this bounce back.  We have had quite a few of these lately, different users trying to email different people.  So I am guessing it is on our side but from the looks of the error it is getting rejected by their server but I don't know how to read them to see why.  I tried to XXX out any important data.

Any ideas?

Delivery is delayed to these recipients or groups:

O'Brien, XXXXX (XXXXXXXX@XXXX.com)

Subject: Easton's Birthday Dinner

This message hasn't been delivered yet. Delivery will continue to be attempted.

The server will keep trying to deliver this message for the next 1 days, 19 hours and 56 minutes. You'll be notified if the message can't be delivered by that time.

The error appears to be because you are listed on a block list according to:

554 Blocked - see https://support.proofpoint.com/dnsbl-lookup.cgi?ip=xx.xxx.xxx.xxx."

Please visit that link (with the real IP Address in) and see why and get de-listed, assuming you aren't doing something wrong or aren't sending spam.  Could be an ancient listing for your IP Address that needs updating.
