Fedora's Exim package ships with a configuration based closely on the
Exim default configuration, but with an optional greylisting ACL which
uses sqlite. If you really wanted, you could adapt it to use MySQL
instead.
The important bit is at
http://david.woodhou.se/exim-greylist.conf.inc
To use it, just set $acl_m_greylistreasons to a text string describing
the reason why the mail was considered suspicious enough to be
greylisted. For example...
warn condition = ${if eq{$sender_host_name}{} {1}}
set acl_m_greylistreasons = Host $sender_host_address lacks reverse DNS\n$acl_m_greylistreasons
warn condition = ${if !def:h_Message-ID: {1}}
set acl_m_greylistreasons = Message lacks Message-Id: header. Consult RFC2822.\n$acl_m_greylistreasons
warn condition = ${if >{$spam_score_int}{5} {1}}
set acl_m_greylistreasons = Message has $spam_score SpamAssassin points\n$acl_m_greylistreasons
require acl = greylist_mail
You'll also want to run something like
http://david.woodhou.se/greylist-tidy.sh
daily, and create the database with
