Plesk 12.x / Linux :: Blacklisted By CBL When Using Domain Names In SMTP

Jul 6, 2014

After upgrading to Plesk 12, I switched on email sending limit to 50 emails per hour per account and also changed mail config to start using domain names in SMTP and less than 12 hours later became blacklisted by CBL - hotmail and live rely on this blacklist - ; the argument was we were sending bots and malware. This server has been under ASL since over a year now and we are positive its clean; still we did a full scan and nothing came up and none of the mail accounts were even close to sending 50 emails per hour. Being sure we were not sending spam nor malware contacted CBL and got whitelisted ..... for less than 24 hours. This happened three days in a row until we switched back to the previous mail settings where domains are not used in SMTP greeting and since then, we haven't had any trouble with CBL. how can we prevent being blacklisted while using domain names in SMTP greetings?

Plesk 12.x / Linux :: Recurring Listing On CBL For Using Several Different EHLO / HELO Names

Jan 14, 2015

I've been plagued by CBL listing for quite some time now, on a linux server with Plesk 12.After months of a fierce fight against every possible malware on the about 120 various websites on this server, extensively monitoring clients emails, enabling restrictive policies and finally even hiring a private security firm to investigate the problems further, we were sure that not a single spam message was sent by our server in any way.

So we finally contacted CBL, exposed the issue and got this answer:The CBL attempts to detect compromised machines in a number of ways based upon the email that the CBL's mail servers receive.During this it tries distinguish whether the connections represent real mail servers by ensuring that each connection is claiming a plausible machine name for itself (via SMTP HELO), and not listing any IP that corresponds to a real mail server (or several mail servers if the IP address is a NAT firewall with multiple mail servers behind it). 54.194.XX.XXX was found to be using several different EHLO/HELO names during multiple connections on or about:

2015:01:09 ~16:30 UTC+/- 15 minutes (approximately 3 days, 21 hours, 14 minutes ago).

The names seen included: xxx1.xx, xxx2.xx, xxx3.xx, xxx4.xx, xx.xxx5.xx, veniceberg.com..Note that the above list may include one or more names that are not fully qualified DNS names (FQDNs). Host names (ie: Windows node names) without a dot are not FQDNs.

The final possibility is that 54.194.XX.XXX is not a NAT firewall, and is instead a single box with many domains provisioned on it, some that send email directly, setting the HELO as the sending domain. If this is the case, to prevent a relisting we strongly recommend setting the mail software on the box so that a single identifying name is used in outbound SMTP connections mail software on the box so that a single identifying name is used in outbound SMTP connections. As an alternate workaround, you can configure the mail software to relay its outbound email through an intermediate mail server. Even a co-resident mail server package (such as IIS on Windows) will do fine.‚Äč

This pointed me to this Plesk Mail setting (not sure if this selection is the default). Now we are waiting a few days to see if changing to "Send from domain IP addresses" solves the issue. I think this is a kind of issue which deserves attention by Parallels to avoid other users go trough our fatiguing ordeals. If this setting is responsible for getting servers blacklisted, it should be highly discouraged.

Domain Names And Hosting

Oct 1, 2009

I have a domain bought with godaddy.com

I have the site hosted on hostultra.com

Whenever I put the address in (.com) it stays as the label in the address bar on every page.

Is having the hosting and and domain with the same company the only way to make the pages say mysite.com/index.html etc ?

Without using masking of course.

Using WHM To Switch Domain Names

Jun 30, 2008

I got abc.com and xyz.com websites hosted on my dedicated server with whm control panel.

abc is my dev site and xyz is my current running live site. Now my dev site is done and I like to launch without uploading files to xyz.com. Both sites are on same server.

So, I am thinking to rename xyz.com to nonexisting.com in whm (site will down at that time). After that, rename abc.com to xyz.com. In order to rename site names, I have to use Main >> Account Functions >> Modify an Account , and edit domain name>>save.

if this is going to work for everything including email settings, ftp etc...

Can You Add Too Many Aliased Domain Names

Jul 10, 2007

Is it possible to add too many aliased domain names on a Dedicated server? I have Hostgator's most powerful dedicated server and I added probably 150 domain names as aliases to one of my websites. Now today all of the sudden none of my other sites will load on the web. When I try to go to one of my sites it just thinks and thinks but never loads.

I'm using WHM with cPanel. Can aliased names cause too much server load? Some of those 150 domains get a little traffic but not much.

Domain Names Not Resolving

Dec 16, 2007

Ocassionally some users have problems to connect the their websites, they can connect to the server via browser and can ping it and tracert the server IPs fine, they can also browse domains having a dedicated IP address. But they can't connect or ping their websites from their end, basically I think the domain name is not resolving.

From our end and the rest of users everything works fine.

Once I get a complain of this type I try whatever I can do

Check to see if their IP is not blacklisted
Restart named service
Restart apache service
But most of the time this doesn't work at all.

Exactly as the problem comes it goes, nothing I did seems to have any effect on the solution. It goes and ocassionally reappears.

Would you suggest me what would I do to find where the problem is and try to solve it.

Odd Domain Names Using My Server IPs

Sep 22, 2007

I have 10 dedicated Ip addresses and recently spotted in my stats for one of my sites, that some odd domain names were mirroring my site. On checking they were using my IP address and displaying my website.

I have no idea how they could have done this.

I changed my sites IP address to anopther in my range, however these domain names still point to my IP and whatever site I have put there.

Someone has said to me it is a form of phishing, but I dont know how they could have done this and whether I can somehow stop this happening. The domains that have kind of hijacked my IP are
ipinikoparan dot com
and
durmakyokyoladevam dot com

odd enough domain names, could someone have set this up and is it some kind of security risk?

Register Good Domain Names

Oct 13, 2008

I found good domain available names and when I tried to register using some webhosting companies they were first shown as available and in the next step of registration they were claimed to be taken. It does not happen with "not so good" names.
I think it happened with whois.net and register.com

So it looks like there is no way to register a good name?

Even when checking whois may have your good domain name stolen.

Can someone comment this and share his/her experience.

Which regetar and whois companies can I use safely?

Domain Names Diferent Servers

Jun 26, 2008

i have two nix vps's One of the vps is setup and running 2 ips, a nameserver and with whm/cpanel on a centos5 system. The other vps is just hypervm with lxadmin panel and one ip. I have nameservers setup on vps1 and all domains work. I would now like to add a domain name to the other vps and use the first servers nameserver. The second vps only has one ip so i wasnt able to setup the domain name there. Is there a guide on how to setup domain names accross two servers with one namesserver. I tried a few options but nothing seems to work.

what do i need to do in whm I already added the domain name to the second vps, i just dont know how to get it to point to first vps and first vps point to domain name.

I know how to work whm but am very new to lxadmin(only two weeks)

Two Domain Names For One Hosting Account

Jan 30, 2007

I have several domain names and I pay for hosting for each domain name. Each domain name gets little traffic, uses little bandwidth, and little storage space. I would like to pay for hosting once and share the bandwidth and storage space amongst the multiple sites. Do you know of a hosting company that offers this? I suppose it would involve having one hosting account and multiple IP addresses that resolve to different folders in your account?

How To Point 2 Domain Names To Same Hosting Account

Apr 4, 2009

I know this question has been asked before but I tried the solutions I could find on net but not total success.

So, I have a shared hosting a/c with a domain(say www.xyz.com) pointing to it ..

Now I want a second domain (www.secondsite.com) to point to www.xyz.com/secondsitefolder

There was this article that says to use 'ZoneEdit' [url]how-to-...ting-aaccount/

And it works but the problem is when someone types www.secondsite.com in the browser, the browser url changes to www.xyz.com/secondsitefolder

Is there someway to stop tht browser url change or what's the correct way to have 2 domain names point to one shared hosting a/c.

Server To Handle 100s Of New Domain Names

May 11, 2008

We are setting up 100s of new domain names every day. We are only hosting a simple blog, in fact with our current setup we are on a HostGator Reseller account and we are just using one account meaning one single cPanel account.

We have a script that automatically runs when people sign up for our service, this script sets up an addon domain on that same single cPanel account with the same document root. Our modified wordpress blog simply looks at the HTTP_HOST in the config file and opens a separate database tables for every new domain name.

The problem we are running into is not the bandwidth usage, nor storage space. But simply the mass addon domains. The cPanel adddomain.html script seems to be getting ran so many times it is overloading the web server.

So I have read about some other people here WHT that are starting to use a new server software that uses a lot less server resources then WHM and cPanel. So I am wondering what hosting companies can provide that sort of a server.

Specifically:

Storage: A couple hundred GB
Bandwidth: 1000s of GB
Server software to run PHP scripts and mySQL databases
Ability to create 1000s of addon domains every day.

Does this need to be an array of servers?

We are ready to get moving on a deal now.

Register Multiple Domain Names Against The Same IP Address?

I have a dedicated server hosted in some data center. The server provider has provided me an IP address. I have bought a a domain name which redirects the traffic to that IP.

Keeping Multiple Domain Names Separate

May 31, 2007

How can it be determined that multiple domains are "affiliated" with each other? For example, at the link below, on the left side of the page it says that yahoo.com, yahoo.net, and yahooligans.com are owned together. Does this mechanism use WHOIS records, or does it use the IP addresses to which each address resolves (which would only get sites that use named-based virtual hosting to the same IP address, right?)

[url]

If people run multiple sites, say personal and business, and they don't want them to be affiliated, how can they make sure they canít be linked with each other through such mechanisms?

Apache :: Two Domain Names With Single Site

Jul 7, 2015

I am currently running Apache on Ubuntu 14.04. I tried adding an alias, but it doesn't do exactly what I need. I have a single site and I need to point two domain names to it. The thing is, if someone types in www.site1.com I want it to show the url as www.site1.com and if someone types in www.site2.com I want it to continue to show www.site2.com in the URL. Right now if they type in www.site1.com it shows the first site name as the URL, but if they type in www.site2.com it changes the URL to www.site1.com. Below is what I have as my virtual host in my conf file currently.

OS - Ubuntu 14.04
Apache/2.4.7 (Ubuntu)

Plesk 11.x / Linux :: Sending Via SMTP Causes Timeout?

Jul 14, 2013

I am using Plesk Panel 11.0.9 (latest updates applied) on CentOS 6.4. at Strato. Unfortunately I can not send email from outside of the server (thunderbird). As I am not familiar wwith mail server configuration at all I would expect that plesk panel does that for me (right?)

* I can send emails via web mail.
* I can receive emails in thunderbird, but sending runs into a timeout.
* The plesk firewall configuration does have a rule for smtp (but I don't see for which port), so I would expect it is not a firewall issue
* I would like to send with some security (starttls and encrypted password), but sending does currently also not work with any combination of (non-)security setting.

My domain has been migrated from another provider, I added it myself via Plesk panel later. The only mail-related change I did without plesk panel was to copy the mailboxes from my old server to /var/qmail/mailnames. But this should not effect sending email...

Plesk 11.x / Linux :: Postfix Smtp Delay

Jun 17, 2014

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)
