Plesk 12.x / Linux :: Postfix - Outgoing Emails Getting Spam
Oct 21, 2014
I have a hard problem with my VPS. I have postfix as mail server on plesk 12 under ubuntu 12.
I dont know why the outgoing mails of all my domains in my servers are getting spam in servers like gmail, yahoo, hotmail...
I'm using mxtoolbox to fix errors and warnings and finally fixed all of them, but my mails are still outgoing to spam.
In mxtoolbox actually I have no mail server errors / warning, u can see it with, for example, this one of my domains: [URL] ....
Headers:
This message is an automatic response from Port25's authentication verifier service at verifier.port25.com. The service allows email senders to perform a simple check of various sender authentication mechanisms. It is provided free of charge, in the hope that it is useful to the email community.

I m trying to get the feature "Outgoing Mail from Exclusive IP Addresses" working, as with an updated Postfix configuration the menu entry for this functions does not appear anymore.
Maybe i am missing something in my configuration that tells Plesk to not show it anymore.
Plesk 12 - fresh installation on Debian Wheezy.
We only changed main.cfnd here is the configuration file (please note that the formatting was a bit corrupted by the plesk panel ):
Code:
alias_database= hash:/etc/aliases
alias_maps= hash:/etc/aliases, hash:/var/spool/postfix/plesk/aliases
append_dot_mydomain= no
biff= no
disable_vrfy_command = yes
header_checks= regexp:/etc/postfix/header_checks
mailbox_size_limit= 0
[Code] ....

I have a plesk 12 panel with outgoing email limit configured to 10 messages by hour.
I have a redirect account (An account named for example A, without mailbox, doing forward to another two internal accounts B and C). I doesn't know if these account are in use for outgoing email, but i think no.
The problem, are, these account are triggering the outgoing limit everyday on some hours. What's going on? Maybe the forwarding action are counting outgoing emails?
I need some method to check account when they trigger the limit to view who messages are trying to send (At least, headers, because i doesn't understand who messages are triggering limit). Also, if the problem are the forwarding, i need a method to not count these messages as outgoing ones, because i understand, if forwarding are triggered by an automated action / internal redirect / received message, these message doesn't are a outgoing one.

My postfix is sending huge amounts of e-mail that I was forced to stop postfix.
Even if I set relaying to closed, disable message submission and disable sendmail spam is still being send..
Outgoing mail control reports nothing at all, and if I check my server with online tools to be sure it is not relaying everything is reported fine.

I just did the update to 12.0.18 #6 and everything seemed to go pretty well. One feature we were really interested in was the Outgoing Spam Filter. Unfortunately, the error I see when I go to that feature reads, "Protection : Not active. There are some problems that prevent the service from being started."
When I Google that error, I'm brought to some KB articles but they are all for the older Outgoing Spam Filter that you need a license key for. I don't believe that is the case any more - if it is, I don't know where to get the key. I will say point out I'm a bit of a Linux novice (we are running CentOS 6.5 on this server), so I'm not really sure where to look....

The problem is that all the mail that exits my VPS server (OVH) is going to the spam folders of Gmail, Outlook, etc accounts.
I've tried to connect my Gmail account to check via POP3 my inbox on my VPS, and all I get is an SSL error.

I have some error when the new outgoing spam protection (limitation for outgoing mail) is enabled. Mail clients are unable to use SMTP for sending mails. "My mail client says: The message could not be sent. You are not allowed to use sendmail utility."
I don't undestand the blocking behaviour since the checkbox "Allow scripts and users to use Sendmail" is checked and no limit is exeeded.This is the relevant log part of maillog:
Code:

Moreover I disabled the line "non_smtpd_milters" in postfix main.conf since my server has same issues discribed in the following thread:

Is it possible to see what e-mails are blocked/prohibited by Plesk Outgoing mail control? Currently i've set a limit of 20 mails on each mailbox. Yesterday I received an e-mail that there were messages blocked. For me personally it would be good to see what the receivers email adresses are and optionally what the content of the e-mail was. This way I can find out if it was really spam or not.
If the e-mails weren't spam, is there a possibility to release and send them?

I am dealing with a situation which i cannot understand. I am running an website for a resort and occasionally i am sending e-mail stop the people who book villas using the website. By occasionally i mean last year i sent 2 e-mail campaigns with a proper spam score.
However, at this moment, even the e-mails that i receive from the website's contact form arrive as Junk into Gmail for example.

So, I have been searching everywhere online and have not come to a fully working conclusion with the issue regarding outgoing emails going to spam via gmail, hotmail, etc.Domain keys are activated, but it seems that domain keys is deprecated, making it useless when it comes to spam detection for email servers such as google, aol, etc.
The only alternative found was here: URL.....But that means that every customers DKIM will have to be created manually via command line. This would be a mission when having over 500+ ongoing customers signing up.Will you guys be implementing DKIM automation for Plesk? I am pretty much against trying to use c(p)anel + Centos and just love Plesk. So I prefer Plesk any day..

My issue started ince a couple of months seemed to increase with update to Plesk 12.0 (though I can't guarantee it).I am using Centos 6.5, all updated. What happens is that postfix usage starts to increase without any apparent reason (during week-ends for example). Then postfix is not responding anymore.

I will wanted to know if hmailserver lets configure the quantity of outgoing emails it is permitted in an hour or minutes. I have found this:
hMailServer is pre-configured to have high security when it comes to relaying and authentication so that no one can use your server to send spam messages.
But I do not know if It refers to what I want or to an antihack or something like that to protect my server.

I would like each of my clients who have a dedicated IP address and an SSL certificate to be able to use their own domain name (and own certificate) when sending mail on ports 465 or 587. I have managed to change the default certificate used by Postfix to my own server's certificate, but I want users to use their OWN IP address and SSL certificate when sending, so this is not an option.
I have been able to update Dovecot to use a specific certificate for each IP address, but I can't seem to update Postfix. I was trying to follow these instructions but my postfix master.cf was quite different than the poster's file and I didn't succeed: [URL] ....
I know many people will simply say "it can't be done" or "just get the users to use the shared IP address", but I know there must be some workaround to make this work, even if it means manually updating the config file after every Plesk update. I'm even prepared (if possible) to have Plesk abandon management of Postfix and have me manage it manually, if that's even an option.

Each migration in the last years I'm running into this bug that Postfix wants to run on port 587 even though this is turned OFF in the Plesk Panel.
Sometimes it does this after some update.
Because another process is running on port 587 this means that postfix does not start and I have some downtime until I "repair" this.
"Repairing" means going into Plesk panel and turning ON SMTP-Auth.... Wait a moment for it to apply and then turning it OFF again....
This unwanted behaviour can be easily reproduced by having this option turned off in the Plesk panel and then running /usr/local/psa/admin/sbin/mchk --without-spam
This will end up in a non-running postfix if another process is already running on port 587.
This shouldn't be happening. Especially because I reported this behaviour years ago..

on a fresh debian 7 64bit openvz system we actually have a problem with the new plesk 12 feature of limiting outgoing mails.We migrated about 25 systems to plesk, this is the first that makes problems.If limiting outgoing mails is activated (i double-checked all possible checkboxes in plesk) a fresh mailbox gives us the following error while trying to send via smtp:
Aug 15 13:09:32 2d4 postfix/smtpd[8645]: connect from unknown[XX.XX.XX.XX]
Aug 15 13:09:32 2d4 postfix/smtpd[8645]: E9AF61C58851: client=unknown[XX.XX.XX.XX], sasl_method=PLAIN, sasl_username=XX@XXX.XX

Aug 15 13:09:32 2d4 /usr/lib/plesk-9.0/psa-pc-remote[8611]: handlers_stderr: SKIP
[code]....
After deactivating the feature all mail is sent without any problems. We use postfix + dovecot.

There are several big domains that frequently defer accepting mail from us causing long delays or rejections. Google, AOL, and Yahoo are examples. I'm considering trying the suggestions found in this online posting regarding rate limiting the sending of messages to those domains. In the below URL, please see the section titled "Different policies for different domains"...URL....
Would these changes be safe to make on a CentOS 6.4 server running Plesk 11.0.9 with Postfix 2.8.4? Would any special modifications for Plesk be necessary?

At this moment, all mail (no matter what domain) goes out straight to its destination. We want to send the mail trough a antispam firewall before it enters the internet.
What setting to change?

I am unable to switch from qmail to postfix via the control panel. It opens a new window that just hangs and never loads. While waiting for it to load, I see these 2 processes running..
root 25108 0.1 0.0 133972 20604 ? S 21:58 0:00 /var/cache/parallels_installer/parallels_installer_CentOS_6_x86_64 --service-mode=components --enable-xml-output --ssl-cert /usr/local/psa/admin/conf/httpsd.pem --branch release,stable --web-interface --with-ssl --disable-browser
root 25109 0.0 0.0 104952 3032 ? S 21:58 0:00 /var/cache/parallels_installer/parallels_installer_CentOS_6_x86_64 --service-mode=components --enable-xml-output --ssl-cert /usr/local/psa/admin/conf/httpsd.pem --branch release,stable --web-interface --with-ssl --disable-browser
But after waiting 20 minutes, the browser never loaded and the two proceses remain. So I killed both processes and removed /tmp/psa-installer.lock and started again. The same thing happened.
Is there a way to fix this? If not, is there an easy way to switch MTAs from the command line?

I've a problem with a server with Postfix. Emails (smtp) are refused by an operator because there is too many mail sent in a few moment.
With Qmail, we make this config :
1) we create file concurrencyremote
# vi /var/qmail/control/concurrencyremote
with the value 3
2) we restart Qmail and it's ok
With Postfix, we make that :
1) we modify the file /etc/postfix/main.cf
default_destination_concurrency_limit = 3
2) In /etc/postfix/transport :
wanadoo.com slow ;
wanadoo.fr slow ;
orange.fr slow ;
orange.com slow ;
laposte.net slow ;
.wanadoo.com slow ;
.wanadoo.fr slow ;
.orange.fr slow ;
.orange.com slow ;
3) After :
#postmap /etc/postfix/transport
4) In /etc/postfix/master.cf :
slow unix - - n - 5 smtp -o syslog_name=postfix-slow -o smtp_destination_concurrency_limit=3 -o slow_destination_rate_delay=1
5) In /etc/postfix/main.cf :
slow_destination_recipient_limit = 20
slow_destination_concurrency_limit = 3
And we modify :
transport_maps = hash:/var/spool/postfix/plesk/transport, hash:/etc/postfix/transport
6) At the end :
# /etc/init.d/postfix reload
But it doesn't work. Operator "Orange" refused emails.
In maillog, we have :
dsn=4.3.0, status=deferred (mail transport unavailable)
