generate a new self-signed SSL certificate for Virtualmin/Webmin

by Lorenz Bausch Posted on April 9, 2014

Virtualmin/Webmin ships with a self-signed SSL certificate. In case you want to generate a new one, here’s how:

openssl genrsa -des3 -out webmin.key 4096
openssl rsa -in webmin.key -out webmin.pem
openssl req -new -key webmin.key -out webmin.csr
openssl x509 -req -days 1095 -in webmin.csr -signkey webmin.key -out webmin.crt
cat webmin.crt >> webmin.pem
cd /etc/webmin/
cp miniserv.pem miniserv.pem.bak
cp /root/ssl/webmin.pem miniserv.pem
service webmin restart

openssl genrsa -des3 -out webmin.key 4096

openssl rsa -in webmin.key -out webmin.pem

openssl req -new -key webmin.key -out webmin.csr

openssl x509 -req -days 1095 -in webmin.csr -signkey webmin.key -out webmin.crt

cat webmin.crt >> webmin.pem

cd /etc/webmin/

cp miniserv.pem miniserv.pem.bak

cp /root/ssl/webmin.pem miniserv.pem

service webmin restart

Virtualmin: Enable Sieve for Dovecot and Procmail

by Lorenz Bausch Posted on July 15, 2013

aptitude install dovecot-sieve dovecot-managesieved

1	aptitude install dovecot-sieve dovecot-managesieved

/etc/dovecot/conf.d/15-lda.conf

# Address to use when sending rejection mails.
# Default is postmaster@<your domain>.
postmaster_address = mail@domain.tld

protocol lda {
   # Space separated list of plugins to load (default is global mail_plugins).
   mail_plugins = $mail_plugins sieve
}

# Address to use when sending rejection mails.

# Default is postmaster@<your domain>.

postmaster_address = mail@domain.tld

protocol lda {

# Space separated list of plugins to load (default is global mail_plugins).

mail_plugins = $mail_plugins sieve

}

/etc/dovecot/conf.d/20-managesieve.conf

service managesieve-login {
   inet_listener sieve {
      port = 4190
   }
}

service managesieve-login {

inet_listener sieve {

port = 4190

}

Edit /etc/procmailrc and fill in the DELIVER parts. It’s important to make continued use of procmail because spam filtering is done there.

# cat /etc/procmailrc

DELIVER=/usr/lib/dovecot/deliver
LOGFILE=/var/log/procmail.log
TRAP=/etc/webmin/virtual-server/procmail-logger.pl
:0wi
VIRTUALMIN=|/etc/webmin/virtual-server/lookup-domain.pl $LOGNAME
EXITCODE=$?
:0
* ?/usr/bin/test "$EXITCODE" = "73"
/dev/null
EXITCODE=0
:0
* ?/usr/bin/test "$VIRTUALMIN" != ""
{
INCLUDERC=/etc/webmin/virtual-server/procmail/$VIRTUALMIN
}
DEFAULT=$HOME/Maildir/
ORGMAIL=$HOME/Maildir/
DROPPRIVS=yes
:0 w
| $DELIVER
:0
$DEFAULT

# cat /etc/procmailrc

DELIVER=/usr/lib/dovecot/deliver

LOGFILE=/var/log/procmail.log
