I did this for a shared hosting system about ten years ago using the ident functionality in Exim. I installed a local ident daemon and then configured Exim to talk to it. Once Exim knew the user, it could apply user-level ratelimiting to both mail submitted via the executable and that submitted via a TCP socket together. If Postfix doesn't have ident support and allowing tcp connections for mail submission is important, you might want to take a look at Exim instead. -- Mike Cardwell https://grepular.com https://emailprivacytester.com OpenPGP Key 35BC AF1D 3AA2 1F84 3DC3 B0CF 70A5 F512 0018 461F XMPP OTR Key 8924 B06A 7917 AAF3 DBB1 BF1B 295C 3C78 3EF1 46B4
