Bug#276074: /usr/sbin/exim4: Add default 50_exim4-config_check_expn

[Jari Aalto]

Package: exim4-daemon-heavy
Version: 4.34-4
Severity: wishlist

Please add following to the default exim installation as
/etc/exim4/conf.d/acl/50_exim4-config_check_expn

The idea is by Marc Merlin (sa-exim author) from page
http://marc.merlins.org/linux/exim/files/exim4-conf/conf.d/acl/70_check_expn

acl_check_expn:

  accept  hosts		= +expn_hosts
  deny	  message	= EXPN not allowed from $sender_fullhost
.ifdef TEERGRUBE
	  delay		= TEERGRUBE
.endif

This would also need:

    acl_smtp_expn = acl_check_expn
