I've an issue where an IP is being found, confirmed from the spam log, on at least one DNS blacklists but the X-IMAIL-SPAM-DNSBL header is only inserted on the first email sent for the same SMTP session where more than one email is sent.

Sample SMTP conversation:
ehlo baddie.com
mail from: first@baddie.com
rcpt to: user@mydomain.com
data
Subject: Test 1
Test 1
.
mail from: second@baddie.com
rcpt to: user@mydomain.com
data
Subject: Test 2
Test 2
.

The email from first@baddie.com will have the X-IMAIL-SPAM-DNSBL header set but the email from second@baddie.com won't.

Any ideas how to correct this?

Cheers.

We implemented a fix in version 12 that resolved some of the issues we were seeing for multiple instance sessions. I believe upgrading will resolve this for you. Thanks

Is there a particular release of V12 that contains the fixes you mentioned?
We' re already on V12.
