Error codes are helpful but not used in sufficiently standardized ways based on
what I’ve seen in our logs.

a month,
but it would be nice to be immediately alerted if postfix logs messages
about such deferrals or blocks. Does Postfix have any native
capabilities good for detecting these issues and acting on them, or
would I just need to do some kind of checks on the pflogsumm output each
day? Obviously

smtp_helo_name=mail-27.redacted.com
We noticed that there were errors in the main mail.log file that referenced
that lines IP address but with a name of 'postfix/error' instead of
'postfix-app1/error', and pflogsumm wasn't reporting those deferrals.
If I grep the mail.log by that lines IP address
that referenced
that lines IP address but with a name of 'postfix/error' instead of
'postfix-app1/error', and pflogsumm wasn't reporting those deferrals.
You did not override the logging from the Postfix error(8) daemon.

Well, it's their policy. I can respect that, if their assumption that

should fall back to IPv4 is valid.
2 - Increase smtp_mx_session_limit (default: 2) so that
I cannot send mail to ISP nines.nl nor to their customers.
Nines.nl have three MX hosts:
two at weight 100, with IPv4 and IPv6 addresses
one at weight 500, IPv4 only
Their primary MX hosts defer all mail sent to their IPv6 address
with 451 Your IPv6 address is not whitelisted at

Doesn't that make the whole ipv6whitelist.eu initiave mistaken?
Or could there be a correct way to use it?
As a side note: they do explain how to enable their whitelisting in Postfix:

This approach is incompatible with 100% RFC-compliant MTAs,
and is therefore broken by design.

on these
ISP's.. I am sure from my experience that the MTA has to be the only best
way to throttle the emails so that i get good deliveries. IP reputation is
clean. All looks good.. just this temp deferrals from these ISP and
sometimes others based on the kind of emails that are send from my org email

Dear Mr. Viktor,
1. Most of the emails get through on the first try,
2. The mails is on an average retried 2-3 times
3. 1/3 of the messages bounce
4. the feedback loop looks clean as the employees of my org only send to
people they know.. thus if you are referring to spam like activity then that

Quantify most. What fraction is that? Out of what overall volume
(msgs/day)?
2. The mails is on an average retried 2-3 times
What is the average time before deferred mail is
22 matches
