Hi :-)

I am running postfix with postgrey.

postfix-2.1.5-3.4 on SuSE Linux and latest postgrey version.

main.cf:
....
greylist = check_policy_service inet:127.0.0.1:10023
....
smtpd_client_restrictions =
         check_client_access hash:/etc/postfix/blocked_ip,
         check_client_access regexp:/etc/postfix/blocked_dialin,
         check_client_access pcre:/etc/postfix/sender_access.pcre
....

Everything works fine so far.

Now I want to greylist ALL mails to certain users. In my company I
cannot greylist all mails.

All mails to user123domain.de should be greylistet but not to all users
. Hope you understand what I mean ;-)

Any ideas ? Perhaps it is obvious but I have not found it yet.

Thanks in advance.

Regards,

PS:

The sender_access.pcre looks like this:

/^([0-9]{1,3}-){4}$/ greylist
/^([0-9]{1,3}\.){4}$/ greylist

# everything with 4 or more dots/hyphens in the hostname
/(\-.+){4}$/ greylist
/(\..+){4}$/ greylist

# stolen from http://sqlgrey.bouton.name/dyn_fqdn.regexp
