[Kolab-devel] [merge67] Introduce postfix helo checking

[Fabio Pietrosanti]

New submission from Fabio Pietrosanti <fp at khamsa.ch>:

# Introduce helo checking (otherwise disabled by default)
smtpd_require_helo = yes
smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, 
reject_invalid_hostname, reject_unknown_hostname, reject_non_fqdn_hostname

In this way a simple and useful antispam feature is added (without breaking anything)
