Hi, 

I got the reject sending through webmail: 
RCPT failed: Invalid recipient [email protected]: 450 4.7.1 
<[email protected]>: Recipient address rejected: Rate limit reached. 
Deferring... 

I've tested with a mail client like Thunderbird and also have the "same error": 
An error occurred while sending mail. The mail server responded: 4.7.1 
<[email protected]>: Recipient address rejected: Rate limit reached. 
Deferring.... Please check the message recipient [email protected] and try 
again. 

The client or webmail gives me an error and doesn't permit sending new e-mails. 
I've checked the postfix queue and doesn't have any message in it.

Hello, 

I'm having problem with verdict configured to DEFER, I always got a reject when 
it reaches the Counter limit. I've tested with HOLD verdict and it works fine. 

I've read some topics about people who also have the same problem, I've tried 
to apply or debug the code, but I'm still not understanding the cause of the 
rejection on DEFER verdict. 

Tried with several versions and still not able to figure out. 
I am using: 

- Ubuntu 10.04.4 LTS 
- Z imbra 8.0.2.GA.5569.UBUNTU10.64 - network edition 
- policyd v2.1.0a 

Downloaded from: http://devlabs.linuxassist.net/projects/policyd/files version: 
v2.1.x-201104210611 
Note: I'am not using the version that cames with Zimbra for now, I've packed 
from the version above and configured the following keys in main.cf: 


smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:10031 

smtpd_recipient_restrictions = reject_non_fqdn_recipient, 
reject_unlisted_recipient, check_policy_service inet:127.0.0.1:10031, 
reject_invalid_helo_hostname, reject_non_fqdn_sender, permit 




I have a basic policy that DEFER all outbound messages to a set of recipient 
domains. 


Here are my confs: 
$ postconf -n 


smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:10031 
smtpd_recipient_restrictions = reject_non_fqdn_recipient,

I appreciate if anyone could give me a light on this issue. Thanks! 



The logs indicate a defer was sent to Postfix for your second attempt...

Where are you seeing the reject?
