451 Error: queue file write error (only when using postfix)

Hi,

I would like to loose a few words, again.
What I'm going to tell is proven bei reality – we administer round about 40 servers with Plesk installed.

1. Plesk has no real Postfix integration. It's a bluff package. Pure marketing. Believe it and stay with qmail. If already switched to Postfix – switch back and stop the pain.

(I'm sorry to say that because Postfix is my favorite, too.)

2. Don't hope for help from Parallels.

I tried to escalate those issues over an Enterprise Platinum Support Contract. This is the most expensive and best one Parallels has to offer. It's over half a year since I told them that this Postfix mess f***s up our business. They don't really care. They are sorry about that. But they are not able to fix this.

So… if you need to stick with Plesk because of customer demands and requests – do yourself a favor and stay with qmail. Even if you dislike qmail and the Bernstein philosophy.
Well, I had qmail, but qmail kept on running high cpu-load, even freezes the server several times. Once upgraded to postfix, that problem was solved. But received another problem instead of it :-(

I'm really looking to other products now. You pay a lot for Plesk, and what do you get. Only a fancy interface.
 
ok, 9.2.2 is out. In the what's new section, only Dr.Web 5 is mentioned. Nothing else!!!

So I asume the postfix issue has not been addressed.

If anyone has already installed it, please tell us if the postfix issue is still present

I obciously messed up with the dates... disregard my last message
 
JFYI:

We've updated all machines to 9.2.2 - nothing to worry about the upgrade but looking for fixes is a waste of time.
queue file write error still exists. just did another update like in KB (with autoinstaller via console) and it again updated postfix. we'll se if this brings good news... (will post it here)
 
smtp proxy

Guys,

My installation has been working great since I modified master.cf file

The problem is with the content filters or smtp proxies, if you remove all lines regarding filtering befire-queue and before-remote you'll be good to go.

This is my complete master.cf file after several modifications:

PLEASE BE AWARE THAT ANY CHANGES ON PLESK MAIL SETTINGS WILL RE-WRITE CONTENT FILTER PROXY OPTIONS.

After these modifications, I've not seen a single 451 Error.

Try it and post back how did it go.
 
@AlfredoP

With your solution it appears you are not filtering your messages with DrWeb or Spam Assassin at all?

Unless perhaps your doing something with procmail maybe.
 
ok, plesk 9.2.3 is out. From the release notes
"Mail forwarding not working and reporting broken pipe error when Postfix mail server is used bug is fixed."

Has anyone tried this release?
 
An more postfix related bugs
"Mail malfunctioning due to buffer length limitation in spam handlers bug is fixed."
"Postfix mail server crashing with segfault error on processing messages with strings larger than 4096 characters bug is fixed."
 
Postfix still doesn't work correctly. Just tried Plesk 9.2.3 with Postfix on a CentOS 5 testing server.
Even on Plesk 9.2.3, Postfix still raises queue file write errors on messages with large attachments (above 5MB), and when Postfix is used, DomainKeys protection is not working.
 
Anyone who has a running system or not switched back to qmail yet should NOT try this update. At least not if it's not older than round about 6 weeks. This avoids headaches.
 
hi,

thanks for all the posted hints.

i am just encountering the same problem - although not by sending email, but receiving.


i've changed as AlfredoP mentioned my master.cf - little addition: i didn't out-coment the pickup line completely.


in any case this is highly disturbing! qmail is not anywhere near beeing an alternative to postfix.

if anyone needs it, here the log part:

anyhow, i hope i got the problem solved and wish for a real fix by parallels
 
I finally decied to do the upgrade to 9.2.3 and ;yckily it worked without a problem. At first I really thought the the postfix problem was fixed too. I did not get any error message for about 2 days. Today it started again!!! This is really strange. Why does it stop for so many hours. and then start again. Would a restart of postfix or psa every 12 hours solve the problem??
 
Would a restart of postfix or psa every 12 hours solve the problem??

i would say probably not I believe there is not just one issue in the handlers & postfix-queue stuff!

There was once a fix which suggested to use the original postfix-queue for me this still works but might be to have other side effects. But my opinion is all the selfmade handlers fom paralles seems to be wired...

ok, it's now about 2 weeks sice the update, and although I do get spradic error messages from postfix, it is nowhere near the amount od errors I got previously.
So 9.2.3 seems to indeed fix this problem almost completely.

I consider this issue solved (until further notice of course, because with Plesk you never know what awaits you...)
 
Any news on this?

It's been three weeks since the last post here. Doess anybody have some new about this issue?
I keep getting those messages, but it's not a matter of the size of the mail, as 21227 Byte should not be to much.
