This was a single message, addresses to 8 recipients, all of which
happen to be you. It is normal that you received 8 copies and they
all look the same.
Looks like your virtual alias mapping or alias maps in MTA or in some milter
or before an MTA rewrote original recipients to steve.
> Is this a bug with Amvisd (possibly exposed my malformed messages)?
Mail header section (and addresses therein) have no effect on mai
delivery. All addresses are sent out-of-band in an SMTP envelope.
Neither amavisd nor an MTA care about To and Cc in a mail header.

Double check your address mappings in MTA.
