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} 
 echo 'queue/postfix-queue' | tee  /etc/e-smith/templates-custom/var/service/{qpsmtpd,sqpsmtpd,uqpsmtpd}/config/peers/{0,local}/90queue-qmail-queue > /dev/null
 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
  • forward email support via .qmail
  • spam filtering to .junk
  • .qmail support using mini-qmail + wrapper and seakablepipe
  • maildrop/procmail support directly via .qmail
  • check /usr/sbin/sendmail -> /etc/alternatives/mta -> /usr/sbin/sendmail.postfix
  • EmailUnknownUser support use luser_relay. if we had virtual domain we could not use it
  • migrate and remove qmail properties to postfix

TODO

  • remove from smeserver-mail /usr/local/sbin/smtp-auth-proxy.pl
  • migrate and rewrite code for smtp-auth-proxy properties
  • make a copy of /var/qmail/control/smtproutes to (su)qpsmtpd/config/smtproutes

FUTURE

  • .foward support, when/if .qmail support is dropped
  • TODO VirtualMail for domain with catchall and EmailUnknownUser ( we can not use luser_relay if we use virtual_alias
  • ldap / AD user support

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