This is only peripherally related to Postfix, but I'm wondering if anyone knows of a very simple SMTP proxy with XCLIENT support. We are transitioning some customers to a new mail server from one that used to serve (outbound) SMTP and POP3 on the same IP address; however, I would prefer not to run a full SMTP service on the new server when we already have perfectly good servers dedicated to this purpose.
I don't need any special features like RBL checks, virus scanning, or SA integration -- our current SMTP servers can handle this as long as they know the client's real IP. Thanks for your suggestions, -- Ben Winslow <winsl...@pa.net>
