Creating a wildcard SSL certificate in Plesk
A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a “*” as the left most label (part) of a domain name, e.g. *.example.com.
A wildcard DNS record in a zone file looks similar to this example:
*.serverbuddies.com. 3600 IN MX 10 host1.serverbuddies.com.
This wildcard DNS record will cause DNS lookups on domain names ending in example.com that do not exist to have MX records synthesized for them. So, a lookup for the MX record for somerandomname.example.com would return an MX record pointing to host1.example.com.
Since version 8.0.1 Plesk allows to create and use certificates for Wildcard domain names (like *.serverbuddies.com.com).
Wildcard certificate can be created the same way that usual certificate is generated. The only difference that you specify the name with “*” sign in the left path, for example *.serverbuddies.com” domain name in the Wildcard certificate will match all this domain’s subdomains, like mail.serverbuddies.com, ftp.serverbuddies.com, etc
Does Plesk support international characters in domain names?
Since ‘Plesk 7 Reloaded’ Plesk includes complete support for the International Domain Naming conventions and their characters.
UTF8 character support is integrated as part of the interface redesign so Plesk will fully recognize characters from Japan, Korea, China, Denmark, Switzerland, Norway, Austria, China, Arabic countries and many other native language characters.

Plesk error: “gzip: stdout: Broken pipe” when attempting to backup domains
Reason: Backup utility failed to write data to disk for some reasons.
Check permissions on backup folder and it’s sub folders. Right permissions are:
grep DUMP_D /etc/psa/psa.conf | awk ‘{print “ls -ld “$2}’ | sh
drwxr-x— 7 psaadm psaadm /var/lib/psa/dumps
Make sure that is is enough free disk space on dump partition.

Spam whitelist limited to 100 addresses in Plesk Control Panel
By default Plesk only allows you to have 100 email addresses listed in your whitelist and blacklists.
It was done to limit CPU usage by spamassassin, because by adding several hundreds of mail addresses into one of the lists user can decrease server performance. Or user can advisedly, add a lot of addresses into list, send a lot of mails and all server will be very slow.
In Plesk CP user can see how many addresses he can add into list(100 minus already added quantity of addresses). If before upgrade to 8.1 (this limit doesn’t exists in earlier version) there were added more than 100 addresses user will see negative number.
HOWTO: Set default site for IP address in Plesk Control Panel
You can select and change which of your Domains your IP address points to by making a simple change in your Plesk Control Panel. This is also useful if you want to preview a site before changing your DNS settings.
1. First, log in to your Plesk control panel,
2. Click on Server.
3. Click the icon for IP Addresses, and you will see a number X under the heading hosting on the far right which indicates how many domains you have on each corresponding IP address.
4. Click on the number you see for the IP address in question.
5. On the next page, you’ll see radio buttons next to each of your domains. Select the radio button for the Domain that you want to see when browsing to your IP address, and then click Set as Default.
Now, when you browse to your IP address, you’ll see the domain that you have selected as Default.
