Hi - I have postfix configured to deliver emails based on custom LDAP queries. One of these queries issues a custom error response.
If an email is received from an upstream server and in the initial lookup, the custom error response is generated, the custom error response is returned properly. eg server-a > postfix > ldap lookup > custom error response returned However, if an email is received from an upstream server and the initial query leads to another LDAP query and then the custom error response, instead of returning the custom error response, the postfix server takes each individual word of the error response and turns that into an expanded email address. server-a > postfix > ldap lookup (mail forwarded to another account) > ldap lookup > custom error response expanded into individual email addresses I can also reproduce this issue if I try to do a test directly from the postfix server. (sendmail -bv emailaddress) The LDAP queries are defined using virtual_alias_maps. The postfix server does not have a need to deliver mail "locally". If the email address is found in the LDAP, then it will use the mail routing information found in the LDAP to redirect the email to the proper server. If the email address is not found in the LDAP then the message can be rejected. tia, =lc
