Plesk 11.x / Linux :: Milter Rejecting Emails Service Unavailable
Jan 21, 2015
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>

I have tried installing Parallels Premium Outbound AntiVirus, but uninstalled it again. The postfix mail server was working before uninstalling. Now I get the following errors:
Code:
Milter reject: 4.7.1 Service unavailable - try again later;
Jul 9 22:17:02 sl1 postfix/cleanup[9308]: warning: connect to Milter service unix:/ctmilter/ctmilter.sock: No such file or directory
This means no mail goes in or out of the system.
When viewing Plesk pannel, everything seems alright.

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:
smtpd_milters = , inet:127.0.0.1:12768
non_smtpd_milters = , inet:127.0.0.1:12768
And restart postfix (/etc/init.d/postfix restart)

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.

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?

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.

I run a dating site, but for some reason hotmail is rejecting certain emails.
When a user receives a message on my site, they get a notification by email to come check their message on the site. This part works, even with hotmail.
However, when a NEW user registers on the site with hotmail, they aren't
getting the confirmation email they would normally get, and as a result they can't join the site. Other email providers get this confirmation email, but not hotmail.

I use CentOS 5.5, Plesk 12 and Atmail. When I log in to
webmail.example.com
by browser and send emails to others, my home computer IP is attached to emails as X-Origin. I even used Thunderbird to send emails and same issue happens.
How can I prevent Qmail or (Atmail) to add my home computer IP to X-Origin? I am even OK if the server IP is attached to emails rather than home IP.

I use a spam protection service. It works as following : -My DNS are configured to point to a server (sever A) which is configured to filter spams. -If an email is not a spam, the first server send it to my mail server (server B).
But some spammers found a way to bypass the protection : They send directly their email to my mail server (server A). So, i want to allow only emails coming from the server A IP.

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.

I am using a Linux server together with Parallels v10.31 ... Unfortunately I get little or no real support from my host so and if I do it's cryptic.
I have been getting a large amount of emails from my server [hundreds daily].
I have attached a screen grab indicating type of email being sent.
I have created only one cron job and that was to reset the RAM on a regular base.
Also is it safe to update to the latest version without a major disaster happening....

After updating our server from plesk 11.5.30 to 12.0.18, one of our subscribers is receiving duplicate emails, a varying number anywhere between 5-15 of the same message!

Started after last update 12.0.18 Update #44 (on CloudLinux): I can send mail wia created mailboxes, but sites can not send mail, contact forms say "Failed to send your message." maillog file also do not indicate sending any messages from domains. Wordpress restore password claims:
"The e-mail could not be sent.
Possible reason: your host may have disabled the mail() function."
php.ini is default:
safe_mode = Off
disable_functions = is empty
The issue about not sending mail from domains was - old versions of LVE anf CageFS are incompatible with latest plesk update, updating them caused all sites in Cagefs to throw error 500 with log string: "SecureLVE jail error Invalid regexps: no match for path to base home directory". It was fixed by changing cagefs.base.home.dirs regexp to the real sites folder location. Enabling cagefs back removed one of the files it shouldn't:
"Removed file /var/cagefs/81/xxx/etc/php.d/soap.ini"
So be carefull to place necesssary files back.
For now everything works.

On my plesk server, i have several emails account. These email addresses should receive only emails send by a specific server. But for now, they can receive any email, including spam.
So, i would like to block all emails that are not coming from the allowed server.
How can i do this in plesk ? As i am not a very good server admin, can you tell me exactly what i need to do in plesk?

I have a brand new and fresh installed server with:
Parallels Plesk v12.0.18
openSUSE 13.1
My Problem is, every day i have to click on activate in the settings of the firewall. Otherwise i have no Mail. The rest (Hosting, etc.) works fine.
No changes in the firewall settings where made, just a migration from my old server.

I just moved from DirectAdmin to Parallels Plesk and already love the interface. Much better than DA in my opinion.
Let's get to the problem:
When I make a new email account I can login to this account on webmail.domain.com (roundcube) and receive and send emails. Now when I want to use this account on Apple Mail i'm not sure which ports I need to use.
For the incoming mail server I use: 143
For the outgoing mail server I use: 587
Now when I look at my mailbox it gives me a warning sign. The outgoing mail server gives a green dot, but the incoming mail server gives me a red dot.
- So sending mails works.
- And receiving mails don't work.
I am using IMAP and have enabled the SSL box. I don't know if i need to check this, because i'm not running on an SSL certificate.
Are the ports that i'm using right? And should I enable the SSL checkbox?
