I have the following configuration for passing email to OpenDKIM for
processing:
[127.0.0.1]:10030 inet n - n - - smtpd
-o local_recipient_maps=
-o virtual_mailbox_maps=
-o virtual_alias_maps=
-o relay_recipient_maps=
-o smtpd_restriction_classes=
-o smtpd_delay_reject=no
-o smtpd_milters=inet:localhost:8465
-o smtpd_client_restrictions=permit_mynetworks,reject
-o smtpd_sender_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o smtpd_reject_unlisted_sender=no
-o smtpd_relay_restrictions=
-o smtpd_data_restrictions=
-o smtpd_end_of_data_restrictions=
-o syslog_name=postfix/dkimmilter
-o content_filter=smtp-amavis:[127.0.0.1]:10032
Since this was implemented, we've had an issue where when emails with a
large number of recipients are processed, the result is that the recipients
get duplicates of the email. We found one workaround to this was to
default_destination_recipient_limit to large value.
Recently, one of our clients found that setting:
-o
receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_address_mappings
Also resolved the problem. I've been reading over the docs, and it seems
that this is a bit aggressive. However, it does seem that at least some
set of these options should be set. I believe it is only necessary to set
"no_address_mappings". Does that seem correct?
Thanks,
Quanah
