https://www.postfix.org/FILTER_README.html states:
> The content filter injects filtered mail back into Postfix with the > Postfix sendmail(1) command, so that Postfix can deliver it to the > final destination. This means that mail submitted via the Postfix > sendmail(1) command cannot be content filtered. Just to confirm: This means that one would need to write a wrapper for Postfix's sendmail binary to have any chance of preventing user Alice to send mail in this manner, while allowing users Bob and Charlie to use sendmail unimpeded? I don't want to assign a non-standard GID shared by Bob and Charlie to the binary itself. If I am missing an obvious alternative, please do share your idea. -Ralph _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
