Sorry, no mailbox here by that name. (#5.1.1)

[error]Sorry, no mailbox here by that name. (#5.1.1)[/error]

Try Following Fix.

Error occurs when you send mail to your Parallels Plesk Panel server,

1) make sure that the mail address to which you are trying to send mail really exists and that the “Mail” service for the domain is enabled.

2) Make sure that the domain to which you sent mail is not listed in the “/var/qmail/control/locals” configuration file. The file must contain the entry, “localhost” only .

3) If DrWeb is installed on the server and has no valid license, make sure that LicenseLimit is set to “pass” in /etc/drweb/drweb_qmail.conf

grep License /etc/drweb/drweb_qmail.conf
LicenseLimit = pass

Can’t Enable/Disable PHP Support for a Domain in Plesk

Plesk control panel has inbuilt feature to enable/deselect PHP support for each domain.

Sometimes, the check box to enable/disable PHP support is grayed out. So the user won’t be able to use that feature. This happens if PHP is not installed or the installed PHP is not recognized by Plesk components. In most cases this happens if you have installed PHP manually


To see the installed PHP components in the following way:

Using Plesk control panel, click on Plesk–>server–>component info, you can see if the installed PHP is detected by the Plesk. The same details of installed (detected) components can be seen using mysql.


mysql -u admin -p’cat /etc/psa/.psa.shadow’

mysql> use psa;

mysql> select * from Components


If you see the value of php as not_installed, you probably have to edit the database to detect the currently installed PHP version. Follow the steps below to do this.

Find out the current PHP version:

php -v

Then, edit the psa components table


mysql -u admin -p’cat /etc/psa/.psa.shadow’
mysql> use psa;
mysql> update Components set version=”5.2.17? where name=”php” limit 1;


Now restarting plesk service.

/etc/init.d/psa restart

Recovering Parallels Plesk panel password

[important]For security purpose Plesk Control Panel have different password set then the server root password.[/important]


Following are the steps to recover Plesk Control Panel Password.

1. SSH to the server as root user.

2. For Plesk version 10.1 and below, you can use following command to check/retrieve password.

cat /etc/psa/.psa.shadow

This file contains your admin Parallels Plesk Panel password
Parallels Plesk Panel 10.2, however, encrypts this file. To view the encrypted file, use the following command:

/usr/local/psa/bin/admin – -show-password

export.php was not found while backing up databases through phpmyadmin

[error]export.php was not found while backing up databases through phpmyadmin[/error]


This error is mainly caused when database size is more and you are trying to backup it up using phpmyadmin.




Increase memory_limit in /usr/local/psa/admin/conf/php.ini to higher value and restart
Plesk Control Panel after that.

Ideally 512M of memory_limit should fix the issue.

error: subsystem: cannot stat /usr/libexec/sftp-server

Unable to connect SFTP  via FTP client on Plesk server.

FTP logs show following:

[notice]sshd[5869]: subsystem request for sftp
error: subsystem: cannot stat /usr/libexec/sftp-server: 
No such file or directory[/notice]
As mentioned in the error, file /usr/libexec/sftp-server was not present. 
To fix this problem you can refer to following steps:

root@office1 [~]#locate sftp-server /usr/libexec/openssh/sftp-server
2) Edit ssh configuration file /etc/ssh/sshd_config and comment 
the line containing "/usr/libexec/sftp-server"

and add new line which
will look like “Subsystem      sftp     /usr/libexec/openssh/sftp-server”

# override default of no subsystems #Subsystem sftp /usr/libexec/sftp-server Subsystem sftp /usr/libexec/openssh/sftp-server
3) reload sshd service

root@server[~]#/etc/init.d/sshd reload

Now try connecting to SFTP. It will work.
