Normally your ISP / mail server (e.g. postfix) will ?stamp? incoming mail using x-original-to or similar to show the actual address the letter was sent to. MailMate prefers such header since the ?to? header is often not reliable, e.g. for this email it?s ?mailmate at lists.freron.com?. The x-original-to is unfortunately not a real standard, so my guess is that the software receiving mail for the aquamacs list add the header (understandable, if fronted by a normal SMTP server) the mailing list software doesn?t strip the header before re-sending it to the list members, and your mail server doesn?t add/overwrite the header (it might use some other header to indicate the original to address of the email). It might be good to see all the headers in the email and know your subscription address to the aquamacs mailing list.
