spam assassin rule to block a From address

    I sometimes use brackets to filter Subject (some times multiple
Subjects). They work.

see one rule I use below . It is for Subject with brackets. Not for From address


file /etc/mail/spamassassin/SPAM_12AUG2016_Subject_1.cf

header SPAMS1 Subject =~ /(special offer|Marketing Strategy|amazing
offer|intake|Enroll Now)/i
describe SPAMS1 Email contains the above words
score SPAMS1 9.0


anyway, I removed brackets this time. Let's see what happens now. I
think \@ is a good point I should think of.

this is my new rule


file  /etc/mail/spamassassin/SPAM_11Oct2016_From_1.cf

header SPAM11OctF1 From =~ /^airecom612\+97d7d60a91d9695c9a4240f92d5c3cae\@/i
describe SPAM11OctF1 From address contains the word airecom612@
score SPAM11OctF1 10.0
