Take a look at:
https://spamassassin.apache.org/full/4.0.x/doc/Mail_SpamAssassin_Conf.html#CAPTURING-TAGS-USING-REGEX-NAMED-CAPTURE-GROUPS

I imagine you should be able to do something like:
header      __CAPTURE_RCPT              To:addr =~ /(?<RCPTA_FULL>(?<RCPTA_LOCALPART>.+)\@(?<RCPTA_DOMAIN>[a-z0-9\-\.]+))/i
header      __TO_IN_SUBJECT             Subject =~ /%{RCPTA_FULL}/i

It works for finding the RCPTA_FULL in body at least. Just note it requires SA version 4.0 or higher.

Hi Gang

I see more and more spam mails with a subject containing the To
email address similar to:

From: [email protected]
To: [email protected]
Subject: Important message for [email protected] - claim your prize

Is there a way for matching such combinations? Has anyone perhaps
created a plugin to search the To: email address in the Subject?

Mit freundlichen Grüssen
