> Can anyone tell me what could be going on here? 1. the message received by amavisd had two or more instances of a Message-ID header field, and this is in violation with RFC 2822; Whether this is a cause for a bounce/rejection/notification is a matter of policy. If it was one of your own domain's MUAs which produced such mail it should be fixed or replaced. 2. amavisd was configured to reject or bounce a message with a bad header. This is not a default setting, and there is usually no good reason to reject such messages. If a message is coming from inside, consider sending the sender a notification. I'd suggest to keep $final_bad_header_destiny at a default setting of D_PASS. Mark
