Thanks Gordon. I'm sorry for the lack of clarity. We have a problem with spam in Webmail local service. Outgoing messages have the address of the sender (From header) with an external domain for example "otherdomain.com" which is obviously not a domain local call "localdomain.edu. This problem causes the external mail systems try to block our messages as spam, which is logical. I need to know which mechanisms to tell Courier that only accepts outbound messages from domains in hosteddomains, local, etc.. It would be like setting smtpaccess by IP addresses, and also by domain of the sender address (From: header "localdomain.edu). I wrote a module for pythonfilter (based on localsenders) using methods IsRelayed and IsHostedDomain except for the backup MXs, that resolves this situation in a hasty, but I do not know if it is an unorthodox way of doing so. I too am intrigued, if this problem is common in mail systems, as this can be a problem on systems that are configured to allow relay for IP addresses but not using SMTP authentication. I forgot!!!, I will review courierfilter.
