Spam Specialist
Barb complained that there were several incoming emails that were sent but that she never received. I dived into the log files for Exim4 on my mail server and sure enough, there were some emails discarded as spam that should have been legitimate. My ISP has its own spam filter (Bayesian, I presume), but I do a second level of spam filtering and mail sorting on my mail server in Exim4.
I traced the problem to a rule in the Exim4 filter file:
$header_subject: contains cialis or
$message_body: contains cialis or
The problem here is that by default Exim4 rules don't check for word boundaries. So any word with the characters 'cialis' in it would be discarded. It turns out that the emails in question were discussing "specialists". D'oh!
