Thank you for your help. I have implemented the change in /opt/zimbra/conf/spamassassin/local.cf and performed a zmamavisdctl restart.
I also had to modify the 72_active.cf rule to match the solution provided here
The emails are still going to junk and the header now reads.
header FH_DATE_PAST_20XX Date =~ /20[2-9][0-9]/ [if-unset: 2006]
describe FH_DATE_PAST_20XX The date is grossly in the future.
The INVALID_DATE flag has only shown up today since modifying the local.cf and adding
X-Spam-Status: Yes, score=6.63 tagged_above=-10 required=6.6
tests=[ALL_TRUSTED=-1.8, AWL=0.674, BAYES_50=0.001,
INVALID_DATE=1.245, MIME_QP_LONG_LINE=1.396, TVD_RCVD_IP=1.931,
score FH_DATE_PAST_20XX 0.0
One more quick question in regards to the SPAM score.
could you please tell me what these lines are a and why they would be giving such a high score.
