DONE
* main domain
* listen only socket
* virtual alias for system, pseudonyms, groups, shared
TODO
* remote SMTP
* smart SMTP
* SSL
* logging
* .qmail support or alternative
* maildrop/procmail support ?
* 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');
