Plesk 12.x / Linux :: Protection From Outgoing Spam - Error
Jul 3, 2014
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:

I have 5 Linux Plesk 12 servers, and I use Spamassassin, usually at a sensitivity of 2 or 3, I also use the following DNS
Blackhole lists: zen. spamhaus. org;b. barracudacentral.org;abuse.rfc-ignorant.org;cbl.abuseat.org;bl.spamcop.net;nomail.rhsbl.sorbs.net
But all of this seems to have minimal effect. I examine spam that comes through which looks very obviously like spam, but Spamassassin gives it a very low score, usually in the negative numbers.
Is SA just not as effective as I thought? Seems like if Gmail, etc can filter spam so effectively, then why can't SA? If there's something I'm not doing right, or what you all do to combat spam with Plesk 12.

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....

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.

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.

Since 12.0.18, when I go to Tools & Settings > Mail Server, I get this error message on the page:
"Error: The limits on outgoing mail will not work for the subscriptions that have IP addresses from the white list. To make the limits work, remove IP addresses from the mail server's white list".
However, the whitelist page just contains 127.0.0.0/8 and ::1/128, and all my subscriptions have an external IP address which is clearly not in the whitelist.

The following recipient(s) cannot be reached:

Server error: '554 5.7.1 <x@xxx.com>: Relay access denied'
When you set the outgoing requires authentication/ advance SSL you get:Send test e-mail message: None of the authentication methods supported by this client are supported by your server.I have tried changing to some outgoing ports to no avail.

After migrating our existing client base from legacy Plesk 9.x servers and Expand to PPA, clients phoned in with mail sending problems. These clients are using submission port 587 because their ISPs intercept port 25.
Existing client, Outlook error message:
"None of the authentication methods supported by this client are supported by your server"
Testing with Thunderbird, error message:
"An error occurred while sending mail. The mail server responded: 5.7.0 Must issue a STARTTLS command first. Please verify that your email address is correct in your Mail preferences and try again."
It seems a "fresh" PPA requires STARTTLS on e-mail clients. It is furthermore confirmed that Thunderbird detects the e-mail server settings as dependant on TLS.
The problem is that TLS doesn't seem to work properly by default.
In order to preserve our existing customer base, we follow: [URL] ....
Bottom line, in your /etc/postfix/master.cf, change the line that says "submission" from this:
submission inet n – - – - smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encyrpt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticate d,reject -o smtpd_sender_restrictions= -o smtpd_proxy_filter=127.$
to this:
submission inet n – - – - smtpd -o smtpd_enforce_tls=no -o smtpd_tls_security_level=may -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticate d,reject -o smtpd_sender_restrictions= -o smtpd_proxy_filter=127.$
then do:
/etc/init.d/postfix reload
This is just a quick fix to get you going and stop the phones from ringing. Ideally we would like to re-enable TLS and have information as to why it is not working.

After I've upgraded Plesk 1.0.18 to latest version, I'm unable to set protection on directories. Plesk say it is set, but it is not. I can access protected directory without pop-up of login-details. Old protected directories work, but for new one added not working anymore. I also tried by conventional way adding .htaccess and .htpasswd files to the directory, but it does not apply either.

How is the Number of outgoing Mails counted by mails or by recipients?
With a limit of 25 mails per hour is it possible to send 25 mails with 200 recipients each before they will be blocked or will one mail with more the 25 recipients exceed the limit?

Since upgrading to Plesk 12 I am experiencing a strange bug:
When enabling the limitation of outgoing email messages, is not possible to RECEIVE emails to a account that is only redirecting the email messages (to a different account which also lies on the server).
I reproduced this behavior on two different servers from which one is a complete reinstall.
The maillog will then show the following error when receiving mails to a redirecting address:
Aug 1 04:04:34 xxxxxx plesk sendmail[16709]: handlers_stderr: DATA REPLY:554:5.7.0 The message could not be sent. You are not allowed to use sendmail utility.#012REJECT
Aug 1 04:04:34 xxxxxx plesk sendmail[16709]: REJECT during call 'limit-out' handler
I can find very few information on this error message, but when disabling the limiting feature, everything works as expected.

I've searched, since about update 37 the outgoing mail control has stopped working for all of my domains. I get a hacker sendmail script uploaded sometimes and it used to catch it. Now it allows them to send and isn't detected them, maxing out my relays.

In the documentation for Plesk 12 there is no information on what is happening if the limit for outgoing mail is reached.
If there is a limit of 50 mails per hour on a mail account and someone is trying to send 60 mails in one hour, what does happen with these 10 mails over limit?
1. Are there send 50 mails and the rest of 10 mails are deleted and will never be sent?
2. Or are these 10 mails sent later?
3. Can there be sent more mails in the next hour or is the mail account now blocked for sending mails?

I upgraded Plesk to 12.0.18 on centos5.8 just because of new feature, Outgoing Mail Limit. There was no problem until I had to increase one of my client's domain limit. I set its Mail Box, Domain & subscription limit to "unlimited", but user get limit exceeded warning again. I search this problem on internet, and the only related article was [URL] .... but I didn't got meaning of "server wide limits".
Where is this feature config file?

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.

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

Plesk 12.0.18 Update #38
Cloudlinux 6.6
Outgoing mail control functions properly for domains, but it does not count or limit subdomains.
For example, if you have a subdomain like:
sub.domain.tld
And an email account on that subdomain, like:
info@sub.domain.tld
Then outgoing mail limits are not applied to that subscription/domain/mail account. You are able to send more emails than the limit.
Also, if you go to:
-> Tools and Settings
-> Outgoing mail control
And try to see statistics for that subscription/domain/mail account, it shows that there are not sent emails, even if you have sent emails. Of course I checked it many hours after sending, or even the next days.

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 have set the values for outgoing mail control low enough to catch the problems without affecting all but one of my clients. I have given him increased limits on certain of his mailboxes.
However when he wants to modify the mailbox, for example change the password he gets the following error.
The maximum number of outgoing email messages (in a pink box)
"The value must be in the range 0..50. Only the Plesk administrator can adjust this setting."
He cannot change the password for this mailbox.
Is there anyway of setting a custom limit on an account and also allow the client to retain the ability to reset his own password.

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.

On the dashboard (intro page) there is the option "Outgoing Mail Control" and there the link "See report". When clicking on "See report" I get a "Warning: Permission denied." error message when being logged in as the full administrator. Is this due to an error in an update or what is going on here?
