-For grey listing with Exim, try the following::
+===== Greylisting with Exim =====
-Install greylistd and add your exim user to the greylist group, make sure /var/lib/greylistd/whitelist-hosts is group readable, configure greylistd (set your delay time in the main greylistd config file and add your own hosts to /var/lib/greylistd/whitelist-hosts) and insert the following into vexim-acl-check-rcpt.conf on Vexim, or for plain Exim, in the master Exim configuration file. For Debian split config, you'll have to figure out which file to add it to yourself ;-)

-Placement of this snippet in the config is important. I place it in my ACL section, beneath the RDNSBL and ClamAV sample sections, so that bad senders detectable by other means still have to get through greylisting when they become delisted or send non-viral email.

Other people put this config before other checks, the decision is yours.
 The commented line was used in the Debian greylistd docs (possibly standard with greylistd) in /usr/share.doc/greylistd/examples/exim4-acl-example.txt, but this ACL didn't apply to the Vexim configuration. There is additional config available elsewhere which shows how to catch mails without an envelope sender. References required.
