How can I setup Exim to pipe all incoming mail to a command (PHP)? and never reject an email?

I'm using Debain squeeze, and Exim4

@mailq except I want all domains, and I use Exim, not Postfix – Petah Nov 3 '11 at 23:28

With a permissive ACL and a pipe transport Do you really mean all incoming mail?

If you want to just write a damn configuration file yourself instead of fighting the Debian way of doing Exim, name it /etc/exim4/exim4.conf - it will override the Debian-specific scattered-in-subdirectories configuration.

Got it working using this config:

primary_hostname =
domainlist local_domains =
domainlist relay_to_domains =
hostlist   relay_from_hosts =

received_header_text = Received: by $primary_hostname id $message_exim_id

acl_smtp_rcpt = acl_check_rcpt

never_users = root

host_lookup = *

begin acl

  accept domains =
  accept authenticated = *

begin routers

  debug_print = "R: receive_router for $local_part@$domain"
  driver = accept
  domains =
  transport = php_receive

  debug_print = "R: send_router for $local_part@$domain"
  unseen = true
  driver = accept
  transport = php_send

  debug_print = "R: dnslookup for $local_part@$domain"
  driver = dnslookup
  domains = ! +local_domains
  transport = remote_smtp
  ignore_target_hosts = :

begin transports

  driver = smtp
  return_path =

  driver = pipe
  command = /var/mailer/receive >> /var/mailer/receive_output.log
  group = mail

  driver = pipe
  command = /var/mailer/send >> /var/mailer/send_output.log
  group = mail

begin rewrite        Ffrsbc
