Hello, I'm looking for a solution for the following requirement:
E-mails send from internal to external should be queued and a script (in whatever language) should be executed, with the senders e-mail address and maybe the mail id as parameters. After the script hast finished successfully (we will take care of that), postfix should forward the e-mail. I already had a look at milter and checked the postfix addon page, but did not find what I was looking for. Then I checked 'postconf | egrep "(pre|command|script)"' expecting that I might find a hint there. And I had a look at the before-queue filter, but as far as I understand the documentation, this filter only deals with mails coming from external. Does anyone has an idea how I could solve this? Thanks for any hints or suggestions, Stefan
