Plesk 12.x / Linux :: Greylisting Log Message - Service Unavailable
Jun 25, 2015
I have a question regarding greylisting.
I activated greylisting on my mailserver and took a look in the logfiles.
The mail are temporary rejected with the following log message / statuscode:
451 4.7.1 Service unavailable - try again later;
Mails from my server to other servers are greylisted with messages like:
451 4.7.1 message delayed, see http://www.greylisting.org ;
452 Greylisted. Please try again after some time.
451 4.7.1 <E-MAIL-ADRESSE>: Sender address rejected: Greylisting in action. Please try again later.
Is it possible to change this log message at my server?
Suddenly my server stop to accept mail from outside. Here you have the logs of mail.info
Feb 20 14:26:02 xxx postfix/smtpd[5581]: 17098E1CCB: milter-reject: DATA from mail2.email-o-matic.com[217.116.24.xxx]: 451 4.7.1 Service unavailable - try again later; from=<empresas@xxx.es> to=<whatever@whatwever.es> proto=ESMTP helo=<mail2.email-o-matic.com>
It seems it is a milter problem as in the line I can read "milter-reject"
Also I have a lot of lines like this:
Feb 20 14:27:34 dv2 greylisting filter[9152]: Starting greylisting filter... Feb 20 14:27:36 dv2 greylisting filter[9154]: Starting greylisting filter... Feb 20 14:27:37 dv2 greylisting filter[9165]: Starting greylisting filter...
I can go to control panel and stop plesk milter but I see these lines on mail.info
Feb 20 14:30:04 xxx postfix/smtpd[8845]: warning: connect to Milter service inet:127.0.0.1:12768: Connection refused
And 4.7.1 still there
Feb 20 14:30:03 xxx postfix/smtpd[7289]: NOQUEUE: milter-reject: CONNECT from 223.179.15.xx.dynamic.jazztel.es[37.15.179.xx]: 451 4.7.1 Service unavailable - try again later; proto=SMTP
Maybe is a port (12768) connection error? How I can test that port?
This KB article does not solve anything as the load of the server is 0.1-0.5 [URL] ....
A temporal fix is to edit /etc/postfix/main.cf file comment these two lines:
Since the last update I am having constant troubles with email accounts when sending or replying to email messages.
This is the message I am getting:-
"error sending your message: Service unavailable - try again later"

I'm running a CentOS 6 server with Plesk 11.0.9 installed. It's only being used for dev purposes with only a couple vhosts running on it. All of the vhosts are using PHP - there are a few WordPress sites and Zend Framework 2 applications running. Up until a few months ago it was also running a high traffic WordPress site, but that's no longer the case.
This server has been running without problems for over a year. A few days ago I first started noticing 503 errors (Service Temporarily Unavailable) on accessing one of the vhosts from the web browser.
I logged on through ssh and noticed the load was a bit higher than I expected (nothing crazy though). All other vhosts using PHP also gave me the same error. The only vhost that was working normal was a Ruby on Rails app (Redmine).
I also did a netstat -napt and noticed many connections from two or three IP addresses. I checked their geographical location and after blocking them through iptables the problem seemed to have gone away.
Now it's a few days later and the same problem started popping up. I checked again through netstat and noticed that again a whole bunch of connections from only a handful of IP addresses were connected to Apache.
When I was digging deeper I noticed that some of those IP addresses were what looks to me like other servers (at least they're running Apache). I'm suspecting they are hacked servers and they're trying to use my server to send spam or some other type of evil.
I just blocked those new IP addresses in iptables and that seemed to have solved the problem for now again, but I want to solve the root of the problem.
So my questions are: 1) How can I find out to what vhost those clients are connected? 2) Why does Apache stop working with not that many client connections, when it used to serve thousands of visitors at the same time when that big site was still running on this server? 3) What could they possibly be using my server for? The first time it happened I thought that they found some leaking WordPress plugin to use to spam people, but today I checked and there's barely anything in the mail queue.
Every now and then I will attempt to load my Plesk 12, CentOS6 Website, and receive the following error:
503, Service Temporarily Unavailable.
It requires a restart of nginx and apache in order to remove the error. It then can come back in a week, or in a few hours. Its completely random. I also can't find anything in the logs.
This started happening after I enabled backups, then later disabled backups because of problems with my backup server. However this does not occur when my scheduled backup was.
All genuine emails are making it through fine - barring one or two domains, which fail with postfix/cleanup[5184]: warning: milter inet:127.0.0.1:12768: can't read SMFIC_BODYEOB reply packet header: Connection timed out
postfix/cleanup[5184]: 5082A22A8E: milter-reject: END-OF-MESSAGE from XX-XX-202-76.dsl.in-addr.zen.co.uk[XX.XX.202.76]: 4.7.1 Service unavailable - try again later; from=<newsalert@financialexpress.net> to=<nameremoved@domain.co.uk> proto=ESMTP helo=<mailrelayname.co.uk>
We have just installed the plesk version 12. All the installation completed without errors . then we restarted the server . and when we tried to open the plesk through the desktop shortcut we get the error " HTTP Error 503. The service is unavailable."
We have tried the following links fix HTTP , kb6735 .
Seems this started when upgrading to a version of 12. It was working a few days ago and only seems to affect mailing lists. I found a google Cached thread here where Igor was assisting some folks as late as Aug 4 and referenced this was "reported to development (PPP-10678 for your reference)" it seems the forums on Parallels changed or something because several Google links are not working and resulting in having to used cached results for the two links below.
I am able to disable SPF and the e-mails go through just fine however this was working with SPF enabled before a recent upgrade.

Deleted a domain workspace in Parallels Plesk and now I am getting this error when signing into the panel:Looked at the logs and been trying multiple commands (including the bootstrapper repair etc.)I found the full error from the logs:

Is it possible to get Plesk working with different bounce message templates? I'd like to make messages in my Polish language to make people know what the bounce problem is. How can I make plesk not to overwrite the main.cf and bounce directive ?
I'm using Postfix 2.7.1 on Debian 6 with Plesk 11.0.9.
Currently the text of a bounce mail shows:
This is the mail system at host example.org.
Your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.
The mail system
<_plesk_bounce_example.org@localhost.localdomain> (expanded from <ttt@example.org>): This address no longer accepts mail.
And I'd like to get rid of address <_plesk_bounce_example.org@localhost.localdomain>.
I added the bouce file template to Postfix's config by:
I'm using Plesk 11 in a Ubuntu 12.04 Linux environment on a remote dedicated server. I am NOT trying to upgrade to Plesk 12. But, every time I log onto the panel, I get the error message shown on the subject line. Afterward, it says, "To solve this problem, send an update log to Parallels support." I have the update log ... but "where" to send it. Is there an email address? A webpage?
I just discovered there is seperate error log for php-fpm and since only 1 site is running fully nginx, the log is full with this error:
"NOTICE: PHP message: PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0"
we regularly get this message in boxmail of adress used to send email from server.This is the mail system at host DOMAIN.fr. You can delete your own text from the attached returned message.The mail system
<1@SERVERNAME.HOSTER.com> (expanded from <1>): User unknown in virtual alias table
If i look in maillog i see that :
May 18 16:48:52 SERVERNAME postfix/error[22737]: F22521B4E45: to=<1@SERVERNAME.HOSTER.com>, orig_to=<1>, relay=none, delay=0.07, delays=0.04/0.01/0/0.02, dsn=5.0.0, status=bounced (User unknown in virtual alias table)
The problem is in error message (at top) the message attached is the one sent to EMAIL@DOMAIN.com. So we can think the message is not sent to EMAIL@DOMAIN.com. SERVERNAME, HOSTER and EMAIL@DOMAIN are here to mask real data.
I attempted to install Zen Cart in a (correctly formed) subdomain and I received this message when the process crashed before beginning: "Non-zero exit status returned by script."
I just configured the limit for outgoing mail. It works well, but I have still some questions.
Normally the server sends bounce messages in HTML and in german. They look nice and what is much more important, the users who do not speak english are informed what is going on.
The message that is send, when the limit for outgoing mail is exceeded uses a different template. It is delivered in plain text and after explaining in german that the mail could not be send, it states the reason in english.
Is there any way to edit this bounce message, so that a translation could be added?
I had some users complaining that the server is not working, because they tried again and again to send a mail and kept the counter over the limit. For they did not understand what was causing it.
The Outgoing Mail Control feature is working fine. One missing option with this feature is to view the contents of blocked messages. Unfortunately, sometimes a site gets hacked and is sending spam. which are over the message sending limit, to try to find out where the message came from.
The current problem is that the email message contents of the limitation warning with subject "Attempts to exceed outgoing limits for domains, mail boxes and subscriptions." is not correct. Somehow it only contains the text: date.timezone = "Europe/Amsterdam" (which is a PHP setting) instead of a descriptive message. I hoped it would contain the blocked message contents or some useful text. Can I change the contents of this message to the what is should be? And what should it be?
It looks like a problem I had ones before where the custom PHP settings at the hosting packages level and at the domains level where replaced with some other kind of settings string. But solved by just changing the custom PHP settings
I have a plesk 11.0.9 on a windows server 2008 R2 which has MailEnable. One of my customers faced a problem to send emails from one of his local mailboxes to another of his local mailboxes! He got this error:Your message did not reach some or all of the intended recipients.The following recipient(s) cannot be reached.Server error: '550 Requested action not taken: mailbox unavailable or not local'
But we are sure the recipient mailboxes exist and work fine!I checked this link: URL....It dosen't work for this case.
I've just recently installed Plesk Panel 11.5. Previously I was using a basic IIS Mail Server with the current server allowed to relay messages for my Web Sites.After installing Plesk, I went to Tools & Settings -> Server-Wide Mail Settings. In there, I have relaying set to Authorization is required (SMTP) and for the relay access I have the following 3 entries:
127.0.0.1/32 ::1/128 <My Servers IP>/32
Whenever one of my sites tries to use this server now to send out mail, I keep getting the following error:Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local...I've been struggling with this issue for weeks now and have read all the documentation and forum posts I could think of, I've restarted the server, I've run C:Program FilesSWsoftPleskadminin>mchk --all --fix=all
The e-mail accounts that I'm using to send mail from has nothing to do with this server and it's domains, I'm just trying to set the mail server to start sending mails like my IIS server used to.I've found the setting to Open Relay on the server and have activated it, yet whenever one of the websites attempts to send a mail, the same response is received.Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local.
