Topic: Retry timeout exceeded

==== Required information ====

- Linux/BSD distribution name and version:
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):
- Web server (Apache or Nginx):
- Manage mail accounts with iRedAdmin-Pro?
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.

Hi,

I have a couple of partners trying to send me email, but they both get their mails bounced back with the same message:

Action: failed
Final-Recipient: rfc822;me@mydomain.com
Status: 5.0.0
Remote-MTA: dns; mail.mydomain.com
Diagnostic-Code: smtp; 451 4.7.1 <me@mydomain.com>: Recipient address rejected: Intentional policy rejection, please try again later: retry timeout exceeded

Should they check anything on their side to make sure they pass the graylist?

Re: Retry timeout exceeded

1) check GREYLIST setings in settings in /opt/iredapd/settings.py
see https://docs.iredmail.org/manage.iredap … l-settings

The default values seems to be
GREYLISTING_BLOCK_EXPIRE   15 minutes  ( all retries before 15 minutes will fail)
GREYLISTING_AUTH_TRIPLET_EXPIRE 30 days  ( remember a passed triplet for 30 days)
GREYLISTING_UNAUTH_TRIPLET_EXPIRE  2 days   ( retries after 2 days cause a new greylist message (this looks like YOUR problem.)
Search in the maillog to find out when and what error codes are returned for the sepecific client/sender/receipient triplet

Re: Retry timeout exceeded

/opt/iredapd/tools/greylisting_admin.py can be used for controling Greylisting for specific senders/recipients

/opt/iredapd/tools/greylisting_admin.py --list-whitelists
/opt/iredapd/tools/greylisting_admin.py --list-whitelist-domains
/opt/iredapd/tools/greylisting_admin.py --list    # list Your addons

    * Whitelist IP networks/addresses specified in sender domain:

        # python greylisting_admin.py --whitelist-domain --from '@example.com'

Re: Retry timeout exceeded

It's better whitelist your friends' mail domains with /opt/iredapd/tools/greylisting_admin.py.
