Projects / postprox


postprox is a minimal Postfix SMTP proxy which copies an SMTP conversation between its input and another SMTP server, but spools the DATA portion to a temporary file and runs a specified program on it before passing it on to the output server. It can potentially output an SMTP error code instead of the data if the content filter says to do so.
