How to block addresses beginning with pipe

any possibility to block messages coming from addresses beginning with 
the pipe character?
I'm getting a lot of messages with spoofed addresses beggining with the 
pipe character like:

Dec 21 14:23:41 smtp2 sendmail[4296]: nBLDNdn0004296: 
from=<|sheldonconciliate at>, size=1615, class=0, nrcpts=0, 
proto=ESMTP, daemon=MTA-v4, relay=[]

I was trying simple rules and also regexps in my spam.blacklist.rules 
like the one below but it filtered out either all addresses or nothing.

Is Definitely Spam = %rules-dir%/spam.blacklist.rules

From:           /^\|.*@.*/             yes

My version of MailScanner is 4.63.1-2

Thank you
