In part one of this tutorial looked at installing and configuring greylistd alongside Exim to help combat the evils of Spam. In this second part I will look at getting some information out of greylistd — handy if you need to troubleshoot why the CEO’s “urgent” message hasn’t arrived yet!

Greylistd is the daemon called by Exim during SMTP connections. The acl_check_rcpt ACL (if setup for greylisting) will ensure that Exim logs SMTP connections resulting in greylisting. You can use this information along with statistics from greylistd itself to troubleshoot and track progress of greylisted sender-triplets and messages.
