If you can't see anything in your logs indicating the message has been received, your best bet would be to get in touch with the sending domains IT and have them investigate. It may be messages are stuck in an outbound queue somewhere, or getting dropped on the outbound.

Yea. that's what i have been trying to do. Unfortunately, one of the domains is Walgreen and their IT so hard to get in touch with. <br />
<br />
Is there anything else i can do on my side? I just want to cover my bases. <br />
<br />
thanks.

Hi. we have at least now, 2 domains sending or replying to emails sent by one of our users and we dont see it come. I dont know where to start troubleshooting because i dont see their replies hitting our filter. The odd thing is that they dont get any errors/NDR either. Its like the email went out from their client and then gone.. <br />
<br />
I have verified that our domain is not listed on any popular spam databases. We also have a Barracuda Spam filter. <br />
<br />
thanks.
