custom spamassasin rules for special cases

[Todor Colakov <to...@inbox.com>]

Hi there,

I'm getting lot of emails(spams), so I tryied to find some common signs. I made some custom rules for most of them, but they are 2 types where i don't know how to progress futher:
1.emails, whose from:addr are all of this shape: 
???<something>???.<same_something>.<1st lvl domain>
exs. 
sefcabanasolhij@cabanasol.com
jircapefearhoghot@capefearhog.us

2.Emails of same header fields To and From. Is there way, how to compare header field against another header field
like To:addr ~= $From:addr
In Perl reg.expr. you can use variable, but not sure how to use it in Spamassasin

Can someone out-there help me with these?
Thank you
Todor
