Hi,

I can't do smtpd_proxy_filter work with pipe (only a test):

-- master.cf --
smtp inet n - - - - smtpd -vvv
-o smtpd_proxy_filter=unix:private/filter
filter unix - n n - - pipe
flags=Rq user=nobody argv=/usr/lib/postfix/filter.sh -f {$sender} {$recipient}

-- filter.sh --
#!/bin/bash
echo x > /tmp/email.eml

-- log --

-- version - Debian Etch --
postconf mail_version
mail_version = 2.3.8

-- /tmp/email.eml permission
ls -l /tmp/email.eml
-rw-r--r-- 1 nobody root 25 2008-01-15 09:07 /tmp/email.eml

Smtpd get timeout and /tmp/email.eml is not created or updated with
"x". I think that filter.sh is not called by pipe. Why?

Ps: original filter.sh implent basic smtp protocol, the current
problem is not being called.
