Check if dovecot/sieve is also connecting to localhost, as you did in
you telnet session (there should be a "smtp connected address=..." line
just before the "smtp failed-command" you posted), and if it's not, try
again using that address.

Posting your smtpd.conf (redacted if needed be) would help. Probably
the messages from sieve are matching the wrong rule. Or try running
smtpd on the foreground, with "-v", to figure out what is going on
(maybe "-v" is overkill, "-d -T smtp -T lookup -T expand -T rules" might
be enough).
