Look at procmail's built-in TO macro. It catches To:, Cc:, Bcc:, and a
few other common ones. Then, that would be
* ^TO(.*\<)?mysql@lists.mysql.com

A more reliable way to match list posts is to look for a list-specific
header. I know that Mailman-based lists put a List-Id: header in any
messages that are sent out to the list, and ezmlm may do the same. Using
this kind of a header will even catch people that BCC the list or
don't have the list address in their headers for some other reason.=20

For example, my procmailrc has the following recipe for vox:=20
:0:
* ^List-Id:.*vox\.lists\.lugod\.org
lugod
