You're probably using address rewriting BEFORE and AFTER the
content_filter (in both smtpd processes).

It's a common misconfiguration:

# content_filter, keine Adressmanipulation vor dem filter

smtp inet n - - - - smtpd
-o receive_override_options=no_address_mappings
-o content_filter=amavisd:[127.0.0.1]:10025
-o smtpd_authorized_xforward_hosts=127.0.0.1
-o smtpd_authorized_xclient_hosts=127.0.0.1

and the other smtpd:

#
# Reinjection smtpd, kein content_filter
# nur mynetworks darf
#

localhost:10026
inet n - - - - smtpd
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o mynetworks=127.0.0.0/8
-o receive_override_options=no_unknown_recipient_checks
-o content_filter=

Take a look at my receive_override_options
