|Summary||0004232: Enabling Greylisting in Endian 2.5 blocks incoming mail|
|Description||Clean install of Endian 2.5. If I configure the SMTP proxy and enable the Greylisting anti-spam feature, incoming mail is blocked and the sending server receives the following:|
SMTP -> FROM SERVER:
451 4.3.5 Server configuration problem
SMTP -> ERROR: RCPT not accepted from server: 451 4.3.5 Server configuration problem
|Additional Information||Turning off the greylisting and restarting the SMTP proxy clears the problem.|
|Tags||No tags attached.|

main.cf [^] (2,214 bytes) 2012-01-04 21:48
postgrey.conf [^] (487 bytes) 2012-01-04 21:48
Unable to reproduce; I've enabled greylisting and tried with:
- only some Whitelist recipient,
- only some Whitelist client,
- both of the above at the same time.
The smtp proxy was always able to deliver emails.
Is it possible to have the details of the configuration?
The problem is with receiving e-mail. The error message I quote above is what the remote SMTP server gets when it tried to deliver e-mail to the Endian box. The SMTP proxy is set to "Active" on RED and "Transparent" on Green.
The configuration is a duplicate of what I had on 2.4.1 and I've wiped and reinstalled the software twice with the same result.
Thank you very much for the information.
I've reproduced your environment as much as possible, but still can't get the error under no circumstances.
If possible, you can provide your /etc/postfix/main.cf and /etc/postfix/postgrey.conf (having care to remove any information you don't want to be made public).
Another thing that you can try, is to check if postgrey is really running:
ps faux | grep postgrey
As a last resort, you can try this:
1. stop postgrey.
2. _move_ any file under /var/spool/postfix/postgrey/ to another directory.
3. restart postgrey.
it's possible that the postgrey db is corrupted.
Files uploaded as requested as wall as section from /var/log/maillog showing test mail arriving first with greylisting off and then with it on.
Postgrey service seems to be running, but there are no files in /var/spool/postfix/postgrey/
A wrong value of the greylist-text parameter in /etc/postfix/postgrey.conf prevented postgrey to start.
Thank you very much for the report; the problem should be fixed in the upcoming efw-smtpscan 2.7.6 package.
