Thanks for information. I am already using a java version of milter which listens to 10099 port for milter support Main.cf file:
# JMilter (info_milter) info_milter = inet:127.0.0.1:10099 milter_protocol = 6 How can I resend the email again, if User allows that. This seems to be little complicated. -/RB From: owner-postfix-de...@postfix.org <owner-postfix-de...@postfix.org> on behalf of Wietse Venema <wie...@porcupine.org> Date: Wednesday, 1 June 2022 at 8:00 PM To: Postfix developers <postfix-devel@postfix.org> Subject: Re: Quarantine message using milter ran...@skurelabs.com: > Hello Folks, > Is it possible to quarantine an email using before > queue milter(http://www.postfix.org/MILTER_README.html). > I would appreciate your help. Yes. Look for a libmilter library funtion called smfi_quarantine() or something similar. The exact name depends on whether you use C, or one of the other language bindings. Upon receiving a 'quarantine' request, Postfix will move the message to the 'hold' queue. Wietse
