Filter on senders name instead of senders address

Hi,

Is it possible to filter on senders name instead of his/her address ?

I'm receiving some spam lately from someone who is using a 
mailinglist.  The listowner says he is not capable (I think he is not 
willing) to block the sender so I want to filter this mail in my .procmailrc.
The senders name is not always the same but the first 5 or 6 characters are 
always, the subject is always different so it can not be used to determine 
the spammer.
Thanks for your help.



Vriendelijke groet,
