I'm working on a DB environment integration with Postfix and have gotten TCP dict lookups to function. Now, I'm working on mail delivery and am trying to determine which method of mailbox delivery to take. I have a few limitations in my application, but for the most part I'm open to all methods. I want to be able to handle quotas inside my application and pass back information to allow temporary or permanent delivery error codes and messages for Postfix DSN. The biggest limitation I have is that I can not assign exit status codes directly from the application. I would have to wrap it in a scripting language and decipher an interim status code to a shell exit code. What are some recommendations to openly handle external mail delivery? I've considered LMTP and mailbox_command but I'm not sure if a pipe service would be more viable. Ideas/suggestions?
Thanks, GlenB
