Description

Koozali SME Server wrapper to configure postfix

Development and testing

 mkdir -p /etc/e-smith/templates-custom/var/service/{qpsmtpd,sqpsmtpd,uqpsmtpd}/config/peers/{0,local}/90queue-qmail-queue 
 echo 'return "queue/postfix-queue";' > /etc/e-smith/templates-custom/var/service/{qpsmtpd,sqpsmtpd,uqpsmtpd}/config/peers/{0,local}/90queue-qmail-queue
 config setprop qmail status disabled
 systemctl stop qmail
 signal-event email-update
 dnf install smeserver-postfix

then test

 echo "This email confirms that Postfix is working" | mail -s "Testing Posfix" emailuser@example.com

or using roundcube/ mail client

to remove

 rm -rf /etc/e-smith/templates-custom/var/service/{qpsmtpd,sqpsmtpd,uqpsmtpd}/config/peers/{0,local}/
 config setprop qmail status enabled
 systemctl start qmail
 signal-event email-update
 dnf remove smeserver-postfix

DONE

main domain
listen only socket
virtual alias for system, pseudonyms, groups, shared

TODO

regression: forward email support via .qmail or .forward
regression: spam filtering to .junk
regression: .qmail support or alternative via .forward
regression: maildrop/procmail support directly or via .forward or via .qmail support
regression: EmailUnknownUser support ( we can not use luser_relay as we use virtual_alias (this might need to add all unix accoutns in this virtual map and also all needed content of /etc/aliases when not returntosender)
switch smeserver-qpsmtpd support to postfix
check /usr/sbin/sendmail -> /etc/alternatives/mta -> /usr/sbin/sendmail.postfix upon removal/update of qmail
.foward support
remove from smeserver-mail /usr/local/sbin/smtp-auth-proxy.pl
migrate and rewrite code for smtp-auth-proxy properties
migrate and remove qmail properties to postfix
make a copy of qmail/config/smtproutes to (su)qpsmtpd/config/smtproutes

TO CHECK $prop->{Blacklist} = $smtp_proxy_rec->prop('Blacklist') || " "; $prop->{Debug} = $smtp_proxy_rec->prop('Debug');
