Postprox is a software that functions as an SMTP proxy by duplicating an SMTP discussion between its input and another SMTP server. It allows for efficient and secure email transmission.
Postprox is a fantastic SMTP proxy that excels in copying SMTP conversations between an input and another SMTP server. However, where it truly shines is in the spooling of the DATA portion to a temporary file for a specified program to process. If the message is to be rejected, postprox outputs an SMTP error code instead.
This software is specially designed to do one thing and do it exceedingly well. That is to proxy SMTP conversations and pass the message contents to another program to determine whether to accept or reject them. Postprox is a minimalist software, and its feature set is kept to a minimum to reduce complexity, effectively reducing the risk of bugs and security holes.
The requirements to run postprox are simple- Postfix and Clam AntiVirus, optional.
The latest release (with some fantastic features) includes the addition of $OUTFILE, which allows filtering scripts to modify emails in transit. Also, putenv() is now used instead of setenv() for better portability. Finally, postprox can capture the IP address of the conversation, the HELO, and the sender/recipient for logging.
Overall, postprox is an excellent software solution for those seeking an SMTP proxy solution that does its job brilliantly without any unnecessary bells and whistles.
