<p class="MsoPlainText">Since last November I've been getting inundated with spam (yesterday just under 7,000 just in the am) from coming from 3 or 4 IP addresses on the same subnet in the morning starting like clockwork just after 9am. Then sometimes I'll
get a similar rush of spam in the afternoon coming from a separate IP range. Countries of origin include US and Bulgaria mostly but also have come from Brasil, Romania and S. Africa.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I've been able to train MailScanner to correctly identify these as spam since the content is very similar -- tons of links to websites with .php extensions. Examples of subject lines: Situations for 2015 that forgive your Student-Loan,
12 month MBA programs, accelerated...<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">To cut down on the processing/traffic on my server I've been just blacklisting these IP subnets at smtp with a deny bounce message. Does anyone have any other suggestions on actions I can take to rid myself of this annoying daily routine?
Does anyone else have similar battle stories like this?<o:p></o:p></p>
