Stock CentOS 7 does not have SMTPS standard. You must create the supervise scripts.

You could stop qmail

# qmailctl stop

and copy smtp supervise scripts to smtps (make sure qmail is stopped or else you'll have a mess):

# cp -Rp /var/qmail/supervise/smtp /var/qmail/supervise/smtps

Then change two files:



QMAILDUID=`id -u vpopmail`
NOFILESGID=`id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
export SMTPS=1

exec /usr/bin/softlimit -m 128000000 \
    /usr/bin/tcpserver -v -R -H -l $HOSTNAME -x $TCP_CDB -c "$MAXSMTPD" \
    -u "$QMAILDUID" -g "$NOFILESGID" 0 465 \
    $SMTPD $VCHKPW /bin/true 2>&1





LOGSIZE=`cat /var/qmail/control/logsize`
LOGCOUNT=`cat /var/qmail/control/logcount`
exec /usr/bin/setuidgid qmaill /usr/bin/multilog \
    t s$LOGSIZE n$LOGCOUNT /var/log/qmail/smtps 2>&1


Start qmail (# qmailctl start)

I just installed qmailtoaster onto CentOS-7.  The qt_install script

port 465 and netstat shows that nothing is listening on port 465.

Can anyone point me at appropriate instructions for setting up listening
on port 465 which are specific (or applicable) to qmailtoaster?  I
searched and found nothing. I did some general
googling and found several somewhat conflicting descriptions but I'm
unsure which apply to the configuration used in qmailtoaster.

My interest is because 465 has been reinstated (in Jan 2018) as the
preferred submission port due to security problems with STARTTLS
