There is a small chance of false positives, i.e. you are catching *all* email 
addresses beginning with airecom612. You could be a bit more specific and 
require a hexadecimal string of at least 16 characters also:
        
        header SPAM11OctF1      From:addr ~= /^airecom612\+[0-9a-f]{16,}\@/i

Thanks. Now I get mails beginning with  "airecom612"


Pls see below


airecom612+97d7d60a91d9695c9a4240f92d5c3...@therealizationofhealth.net
airecom612+eceaaa167743dd4a58b54bdb17ef8...@holistictips.net
airecom612+97d7d60a91d9695c9a4240f92d5c3...@therealizationofhealth.net


So I have changed the rule in this way. pls see below. ( this time i.e
-   /^airecom612.*\@/i )

file /etc/mail/spamassassin/SPAM_11Oct2016_From_1.cf


header SPAM11OctF2 From:addr =~ /^airecom612.*\@/i
describe SPAM11OctF2 From address begin with the word airecom612@
score SPAM11OctF2 10.0


Hope. this will catch the PATTERN beginning with  "airecom612".


your comments on this ?
