Topic: Message reject detail

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release):  0.9.9
- Linux/BSD distribution name and version: Debian 9
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

I installed pflogsumm so that every day I receive an email with the details of the activities of my Mail Server. I'm mainly interested in understanding the number of messages discarded by the server. In particular:

message reject detail
---------------------
 RCPT
   Helo command rejected: Host not found (total: 2)
          2   198.252.108.183
   Recipient address rejected: Intentional policy rejection (total: 60)
         56   vincenzo@server.eu
          1   piero@server.eu
          1   ilaria@server.it

Is there an easy way to go to view the senders of 4xx errors without needing to analyze the log directly? Thanks for your help.

I'm afraid that analyzing the log file is the only way.

Re: Message reject detail

Why do I still not receive emails from this sender? This is the log:

Dec 25 09:37:05 mail postfix/postscreen[13573]: CONNECT from [83.158.4.26]:60656 to [xxx.xxx.xxx.xxx]:25

I added on top/etc/postfix/helo_access.pcre

/^smtp1\.iliad\.it$/ OK
/^smtp1\.proxad\.it$/ OK

and executed the command:

python wblist_admin.py --add --whitelist 83.158.4.26 @iliad.it @proxad.it

what am I doing wrong?

You did it right.

This is greylisting, you can ignore it. FYI:

Unfortunately I had to deactivate the greylisting... 24 hours later I have not received any mail from that domain. As soon as I deactivated it came immediately.
