Thanks, but I did not understand the relationship between the error in the MySQL query and the problem with name resolution.

The messages are being returned to the double-bounce@smtp01..... because of the problem in MySQL query?

Unfortunately I read the other topics but did not understand how to fix it. I will update this server with the latest versions of iRedMail-Pro, but wanted to make it running smoothly first, because it is a production server with many domains.

I hope your help.

Very Tks.

This log message makes sense.

Please follow this forum topic to solve it:

How many messages are, I tried to get only a piece of log to see if I can improve the information:

See who has something different that is not normal:

Aug 13 07:28:15 smtp01 postfix/proxymap[2171]: warning: mysql query failed: Illegal mix of collations

What would it be? It will be another problem, unrelated to what I'm referring?

Very tks.

- Please always paste full original log message instead of part of them.
- Any other related log in Postfix log file?

Hi Zhang,

I'm having a problem that can not find the reason.

I have seen very often the following error when trying to send mail from one user to another of the same domain:


>> 'Andres' on 13/08/2012 08:45
>>
>> <userdomain@domainexample.com> >> 451 4.3.0: Temporary lookup failure


(I changed the primary domain server for the domainexample.com)

When analyzing the queue every day there are a large number of messages, as follows:

A0612341D3     1430 Wed Aug 15 11:57:26  double-bounce@smtp01.domainexample.com
--More--

The content of these messages is always this:

<postmaster@smtp01.domainexample.com>: address resolver failure
recipient=postmaster@smtp01.domainexample.com
offset=206
status=4.3.0
action=delayed
reason=address resolver failure

Bind9 is installed and functioning normally. The file / etc / resolv.conf looks like:

nameserver 127.0.0.1

The file /etc/hosts is:

127.0.0.1       smtp01.domainexample.com smtp01 localhost


I have configured the server about 80 domains and very often these errors occur for users of these domains.

Some hint of what might be wrong?

Tks,

M Martinatti
