Almost. &nbsp;Contacting the sender is not viable, however the custom message is also in the SMTP log! This gives me a chance of finding it.

I administer an Exchange 2007 server. &nbsp;I have set up antispam, and are using 4 blocklists. We have seen a few cases of legitimate email being blocked (in one case Gmail). &nbsp;It seems that one (or more?) blocklists is a tad agressive. Problem is, once the user gets back to me, the IPs in question are no longer lised anywhere, so I cannot tell which block list is causing problmes. <br />
<br />
Is there any way i can set up some sort of logging to determine which block list was used? <br />
<br />
Thanks.
