The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Postfix emails deferred

Asked by drazen_nikolic in Email Servers, Web Servers, Network Security

Tags: , , , , ,

We have Web server with Java web application running on OS: Centos 5, Kernel: 2.6.18-8.1.10.el5PAE. On the same server Postfix is running as well. We sent emails from Java application to Postfix (on the localhost:25).

The problem we experience is delayed delivery of sent emails (e.g. emails are received with 10-60 minutes delay). But, some mails are sent immediatelly.

In the mailog, for the mail which had a delayed delivery, we have found next:
Jul 21 06:54:42 web-system postfix/smtpd[5607]: connect from localhost.localdomain[127.0.0.1]
Jul 21 06:54:42 web-system postfix/smtpd[5607]: C168B93808C: client=localhost.localdomain[127.0.0.1]
Jul 21 06:54:42 web-system postfix/cleanup[5610]: C168B93808C: message-id=<5840482.421216637682746.JavaMail.tomcat@web-system.local>
Jul 21 06:54:42 web-system postfix/qmgr[31232]: C168B93808C: from=<support@site.com>, size=990, nrcpt=2 (queue active)
Jul 21 06:54:42 web-system postfix/smtpd[5607]: disconnect from localhost.localdomain[127.0.0.1]
Jul 21 06:55:02 web-system postfix/smtp[5611]: C168B93808C: to=<user@bluewin.ch>, relay=none, delay=20, delays=0.04/0.07/20/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=bluewin.ch type=MX: Host not found, try again)

...
Jul 21 07:12:19 web-system postfix/qmgr[31232]: 9F28E938094: from=<support@site.com>, size=7337, nrcpt=2 (queue active)
Jul 21 07:12:19 web-system postfix/qmgr[31232]: C168B93808C: from=<support@site.com>, size=990, nrcpt=2 (queue active)
Jul 21 07:12:29 web-system postfix/smtp[5654]: C168B93808C: to=<isystem@site.com>, relay=mx1.barracuda.cubed3.net[66.165.181.230]:25, delay=1067, delays=1057/0.08/10/0.11, dsn=2.0.0, status=sent (250 Ok: queued as 8E996E05CB)
Jul 21 07:12:30 web-system postfix/smtp[5652]: 9F28E938094: to=<user@kabelmail.de>, relay=relay.kabelmail.de[194.25.41.11]:25, delay=88669, delays=88659/0.08/11/0.15, dsn=4.7.1, status=deferred (host relay.kabelmail.de[194.25.41.11] said: 450 4.7.1 Access denied. IP name possibly forged [66.165.xx.xx] (in reply to MAIL FROM command))
Jul 21 07:12:30 web-system postfix/smtp[5653]: C168B93808C: to=<user@bluewin.ch>, relay=mxbw.bluewin.ch[195.186.19.144]:25, delay=1068, delays=1057/0.05/11/0.63, dsn=2.0.0, status=sent (250 <23/A0-24955-61F64884@mx14.bluewin.ch> Mail accepted)


Why the mails were deferred and why the hosts were not found? Also do you have an idea why from relay.kabelmail.de we got "Access denied"? How to make mail to be sent immediatelly?
