Hy! I want to write an after-queue content filter for my postfix installation which is invoked by spawn (according to the FILTER_README from postfix.org).
My problem is, that the input/output part simply does not work. I am sending a "220 localhost SMTP foo" to STDOUT at the beginning of the script, but somehow, this never reaches the SMTP client in a correct way. Has anyone ever managed to accomplish such a soultion? cheers Mathias P.S.: I am using posstfix 2.4.5 and php-5.1.2
