Hi,
I'm trying to limit email in postfix with policyd using AccessControl and
Quotas modules.
The logic that I want to implement is the following:
- postfix smtpd_recipient_restrictions checks first with policyd
(check_policy_service) and after reject
- postfix smtpd_end_of_data_restrictions checks only with policyd
(check_policy_service)
- policyd has access control for permitted sender/recipient and relative
policies with verdict "OK" (used in smtpd_recipient_restrictions)
- policyd has quotas limits on sender or ip and relative policies with
verdict "reject" (used in smtpd_end_of_data_restrictions)
This doesn't work for the following reasons:
- AccessControl has module priority of 90
- Quotas has module priority of 50
- AccessControl in RCPT protocol_state returns PROTO_OK with response 'OK'
and CBP_STOP (so Quotas never inserts the tracking information)
I've seen some bugs about Quotas module related with perl 5.10 (that i have
installed on CentOS6), but simply applying the following patch I obtain
what I want:

# User plugin info
our $pluginInfo = {
name => "Quotas Plugin",
- priority => 50,
+ priority => 95,

cleanup => \&cleanup,
Can I've introduced some bugs or malfunctions with the patch above?
Are there better methods to achieve what I want?
Thanks,
Best regards
