Policyd failed is a known issue, it might happen some times due to apt repository related reason. You can try to install policyd manually before installing iRedMail, but please leave MySQL root password empty. And then install iRedMail.

- Not sure why apache related config files were missing.
- About roundcube, could you please paste related log here to help troubleshoot? it should be /var/log/mail.*.

the failure in the startup of dovecot is related to the options mail_uid, mail_gid and ssl it doesn't recognize
commented those three... started dovecot

now trying to access https://server/mail , getting the certificate error... adding the exception and then all I get is the error page

Not Found

The requested URL /mail/ was not found on this server.

/etc/apache2/sites-enabled/default-ssl doesn't show any of the required redirects, but even if it would it wouldn't help as
server:~/iRedMail-0.7.0-beta1# ls /usr/share/apache2
build  default-site  error  icons

does not show roundcube or whatever...

also /var/www dowsn't show a thing:
server:~/iRedMail-0.7.0-beta1# cd /var/www
server:/var/www# ls
index.html  robots.txt

another fail... I will wipe the system and prepare it for the next try

Sorry for the long post, I just wanted to provide you with all I did from the clean installation on.

As you suggested I did not set a password during the mysql installation (empty password), but as I am forced to provide one in the iredmail installation I had to set one there. However, it will be the same error regardless of me installing mysql beforehand not setting a password or letting the iredmail script handling it. The result is identical.

I wiped the 0.7 trial from this morning already, but the attempt with 0.6.1 on a identical machine this morning shows:
ii  dovecot-common                          1:1.1.16-1~bpo50+1       secure mail server that supports mbox and ma
ii  dovecot-imapd                           1:1.1.16-1~bpo50+1       secure IMAP server that supports mbox and ma
ii  dovecot-pop3d                           1:1.1.16-1~bpo50+1       secure POP3 server that supports mbox and ma

Still... the dovecot issue isn't my biggest concern as I can still make it run... the fact that all the web interfaces are not being installed and also the config file in sites-enabled isn't set correctly bothers me more.

you can try check out the newest version of iRedMail.

you no need change the ports, because the iRedMail would add it auto.

you only need

1:modify the hostname

2: run iRedMail script.

Are you use virtualbox?

User have report when install iredmail in virtualbox and have problem.

Please check my email.

Installation completed on your VPS. You can find config in /root/iRedMail-0.6.1/iRedMail.tips.

I use below lines in /etc/apt/sources.list:

deb http://http.us.debian.org/debian lenny main
deb http://security.debian.org/ lenny/updates main
deb http://volatile.debian.org/debian-volatile lenny/volatile main contrib non-free

Works well, installation completed without any error.

So, i think it's better to follow official installation guide STRICTLY.
It's recommended to make sure you have a working iRedMail server first, then
upgrade Jinja2 or other components if you want.

An easier way to upgrade python-jinja2:

# easy_install Jinja2
