====== Greylisting in postfix with postgrey ======

===== Instalation =====

===== Configuration =====

/etc/default/postgrey:\\
POSTGREY_OPTS="--delay=60 --inet=127.0.0.1:60000"\\
\\
# the --greylist-text commandline argument can not be easily passed through\\
# POSTGREY_OPTS when it contains spaces.  So, insert your text here:\\
POSTGREY_TEXT="Greylisted for %s seconds [see  http://postgrey.schweikert.ch/help/%r.html ]"\\
\\

If you did not add "permit_mynetworks and permit_sasl_authenticated" you should add "localhost and 127.0.0.1":\\
