If you want to change Plesk mailbox directories please review this technical article for guidance.
mkdir -p /home/var/mail
rsync -avz /var/mail /home/var/mail
Connect to the server using SSH/RDP.
Find what SMTP and IMAP/POP3 servers are in use:
# /usr/local/psa/admin/bin/mailmng --features | egrep 'SMTP_Server|IMAP_POP3_Server'
$features['SMTP_Server'] = "Postfix";
$features['IMAP_POP3_Server'] = "Dovecot"; $features['SMTP_Server_package'] = "postfix"; $features['IMAP_POP3_Server_package'] = "dovecot";
Stop the SMTP service:
# service postfix stop
Open the file /etc/psa/psa.conf and change the PLESK_MAILNAMES_D variable:
specify a new location for mailbox directory so that it is like:
# grep PLESK_MAILNAMES_D /etc/psa/psa.conf PLESK_MAILNAMES_D <new_mailnames_directory>
Note: To avoid performance degradation, the new location for the mailboxes directory should be located in the local file system - it should not be mounted as a network share, such as NFS.
Move mailboxes from the current directory to the new location with the
# cp -ap /var/qmail/mailnames/* <new-mailnames-directory> If dovecot is in use, set the new location in the file /etc/dovecot/dovecot.conf by modifying values in the lines below:
# egrep 'mail_home|mail_location' /etc/dovecot/dovecot.conf mail_home = <new_mailnames_directory>/%Ld/%Ln mail_location = maildir:<new_mailnames_directory>/%Ld/%Ln/Maildir
Restart the dovecot service:
# service dovecot restart
After all the steps are done, start SMTP service and reconfigure mail settings using the mchk utility:
# service postfix start
# plesk repair mail
Before creating new mailboxes on new domains configure SELinux in the following way:
following is not required for selinux disabled server.
# chcon -R -t mail_spool_t <new_mailnames_directory>
