Restoring Mail Configuration
Sometimes, Plesk mail server configuration becomes corrupt and it is necessary to
restore it. The restoration is carried out by internal mchk utility, intended for use by
Plesk Control Panel. However, as administrator, you can use it for restoring the Qmail
and Courier-imap configuration when needed.
By default mchk is running in the background mode. To execute it in the foreground,
use the -v option. For example:
/usr/local/psa/admin/sbin/mchk -v
Note: You may not wish to restore SpamAssassin settings for mail accounts, as it
requires running Perl interpreter. To speed up restoring use the --without-spam
option.
Installing Custom SSL Certificates for
Qmail or Courier-IMAP Mail Servers
To securely exchange mail data with Plesk server, you may need to install custom SSL
certificates on the Plesk server. Specifically, SSL certificates can be installed for the
Qmail mail transfer agent and the Courier-IMAP mail server that supports the IMAP
and POP3 protocols.
To install custom SSL certificates, you need to download the certificates to the Plesk
server and then replace the installed default SSL certificates for Qmail and Courier-
IMAP servers with the downloaded custom certificates.
This section describes procedures for installing custom SSL certificates for Qmail and
Courier-IMAP servers.
