Remove MailMan from Plesk
Login to your Dedicated-Virtual Server using SSH as the root user. Now lets run the command to find what version of mailman is currently installed.
You should find results similar to the following
mailman-2.1.1-5
mailman-2.1.1-7.legacy
Now we will use rpm to uninstall
rpm -e mailman-2.1.1-5
rpm -e mailman-2.1.1-7.legacy
Enable Mailman in Plesk
The following steps will show you how to enable Mailman.
1. Login to Plesk.
2. Click on Server.
3. Click on Set Up Mailman.
4. Configure Mailman by providing the Mailing list administrator’s email and password.
5. Once you hit OK you should be taken back to the server page with the message letting you know that the Mailman icon will no longer be accessible.

How can I lower the TTL value in Plesk?
1. Login to Plesk.
2. Click on Domains.
3. Click on the domain for which you wish to lower your TTL.
4. Click on DNS Settings.
5. Click on SOA Record.
6. Set the desired TTL value.
TTL, or Time-to-Live, is the length of time for when a zone file is set to expire. This is usually expressed in number of seconds.
If you ask your local DNS server (usually provided by your ISP) for an Internet address, the server will figure out where to find an authoritative answer. Once provided the answer, it will keep the answer in a local cache so that if you, or someone else, ask for the same address again it will not need to make the request again.
When domain administrators configure their DNS records, they decide how long the records should remain in remote caches. Typically, a remote server will only cache those records for the length of time specified by the TTL. After that, the remote server will remove the zone file from its local cache and ask again for an authoritative answer. Due to this, shorter TTLs can cause heavier loads on an authoritative nameserver.
How to set up one domain to be your DNS in Plesk
You must first have the domain you wish to make your DNS already set up in Plesk. You will also need at least 2 IP’s to use for your server. For reference, in this article ’serverbuddies.com’ will refer to the domain name you are using. Make sure to replace this with your actual domain name.
1. Log into your Plesk control panel as Administrator and select the domain from the Domains list you wish to make DNS.
2. Select the DNS icon from your services list.
3. Select the link serverbuddies.com from the Host list, with Record Type NS and Value ns.serverbuddies.com
4. In the Enter nameserver field change the ns.serverbuddies.com to ns1.serverbuddies.com and select OK.
5. From the Tools area select Add Record. For Record type select NS and enter ns2.serverbuddies.com in the Enter nameserver field and select OK.
6. Select from your host list ns.serverbuddies.com with Record type A and change the value to ns1 and select OK.
7. From the Tools area select Add Record again. For Record type leave as A, in the Enter domain name add ns2, in the Enter IP address enter your second IP address that you are going to use and select OK.
8. You should now have 2 Record types with the NS value of ns1.serverbuddies.com and ns2.serverbuddies.com and under the Host list you will also have ns1.serverbuddies.com and ns2.serverbuddies.com with the Record type of A and they will have 2 separate IP’s.
In order to have these added as DNS values for when you add new domains you will need to change the default DNS record in Plesk.
1. Select Server from the list on your left.
2. Select the DNS icon from the Services list.
3. From the Host list select with record type NS and enter ns1.serverbuddies.com in the Enter nameserver field and select OK.
4. From the Tools area select Add New Record. Change the Record type to NS and in the Enter nameserver field input ns2.serverbuddies.com and select OK.
If you want to use 2 separate domains for your DNS this is even easier, because Plesk has already created this for you. You must have 2 domains entered in Plesk and assigned separate IP’s. You would then only need to create a DNS zone template the same way described earlier, only inputting ns1.serverbuddies.com and ns2.serverbuddies.com for your default values.

Enable Alternate Port other than 25 or 587 (via SSH) in Plesk
Make a copy of /etc/xinetd.d/smtp_psa. For this walkthrough the new filename created is smtp_nonstandard. A command like this should work:
cp /etc/xinetd.d/smtp_psa /etc/xinetd.d/smtp_nonstandard
Add these lines to the copy you just made:
vi /etc/xinetd.d/smtp_nonstandard
type = UNLISTED
port = 2525
and change the service name to match the name of the file. A sample smtp_nonstandard looks like this:
service = smtp_nonstandard
type = UNLISTED
socket_type = stream
protocol = tcp
port = 2525
wait = no
disable = no
user = root
instances = UNLIMITED
server = /var/qmail/bin/tcp-env
server_args = -Rt0 /var/qmail/bin/relaylock /var/qmail/bin/qmail-smtpd /var/qmail/bin/smtp_auth /var/qmail/bin/true /var/qmail/bin/cmd5checkpw /var/qmail/bin/true
# Restart xinetd:
/etc/init.d/xinetd restart
# You should now be able to send mail through your server on port 2525. You may pick a different port if you use this method. We suggest choosing a high port number to avoid using commonly used ports on the internet.
