This lines must exist in your postfix main.cf file:

sender_canonical_maps = hash:/usr/local/etc/postfix/canonical_sender
virtual_alias_maps = hash:/usr/local/etc/postfix/virtual

Substitute '/usr/local/etc/postfix/canonical_sender' and second path for your path to 'canonical_sender' and 'virtual' files - which must exist. Than try to restart (or reload) your postfix server.

This is my problem is that I do not know the path that must include

This looks like you never ran install.sh at all, or it failed. We would need to see the errors from the failed run to be helpful here.

Oh, I see now looking over the thread again that you're on Ubuntu 7.10.

The GPL install script only supports Debian 4.0 and CentOS/RHEL 4/5 and the Professional one also supports Ubuntu 6.06LTS. We won't be supporting any non-LTS versions of Ubuntu. You'll have to install manually--which means you probably need to know how all of these services work...or at least have some UNIX/Linux experience. I'd recommend going with one of the supported systems and using install.sh.

Hi,
please try

echo "virtual_alias_maps = hash:/etc/postfix/virtual" >> /etc/postfix/main.cf

It works for me

I couldn't help but butt my head into this... ---

Try the following fix:

Either edit the /etc/postfix/main.cf file and add:
virtual_alias_maps = hash:/etc/postfix/virtual

OR you can go to Server > Postfix Mail Server > Virtual Domains

Domain mapping lookup table: hash:/etc/postfix/virtual

This wasn't set properly in the install of VirtualAdmin on my system...

We've just fixed a bug in the next version of virtualmin-base (part of the automated installed process) that will actually notify Webmin of the changes that happen during Postfix configuration. Interestingly, on Debian/Ubuntu systems, when fresh installed, Postfix reports this problem--but, in fact, has already been configured correctly. Browsing to the Postfix Virtual Maps page and then checking configuration again solves the problem (you don't even have to touch anything...just look at the page). Subtle bug. ;-)

Postfix virtual maps : No map sources were found in the Postfix configuration

I running Hardy same issue popped up. Followed howtoforge.com for perfect server setup. have apache2, mysql, postgresql, dovecot the whole setup. Working perfect! I use webmin, decided to try virtualmin. I checked all the settings recomended on this page and some others. The issue for HARDY was in apache modules... hash:/etc/alias was already there, action and suexec were already configured, I checked the vhost_alias module in apache global configuration, configure apache modules. Thanks to the fourm I was able to get going in the right direction. Hope this helps!
