The primary purpose of this release is to incorporate the latest version
of Horde Webmail Groupware (version 1.2.7) into Exim4U's Webmail
Groupware. Most of the other changes are of minor significance except
for a change to the exim configuration file (exim.conf) that causes
sender address callout verifications to be performed only for spammy
mail (spam score > 0).
