CentOS Mail Server with Virtual Domains Howto

[morenz]

Hi folks!
I'm new to the forum. It's my first message, 'cause I made a lot of browse in these months...

So, what's my problem?
I'm following the "Virtual Users With Postfix, PostfixAdmin, Courier, Mailscanner, ClamAV On CentOS" howto to set up a mail server.
I just finished to build up a 3-domain mail server with aliasing without database (it's just a small business...), but I realized that I needed DB support 'cause I ran into duplicate users (i.e. info@domain1.tld, info@domain2.tld, etc.) and the sole /etc/aliases file could not make me manage this issue.

I executed all steps, but when I try to run
sudo rpmbuild -ta courier-authlib-0.58.tar.bz2
I get the following response (I will translate, my system is in Italian):
dependencies compilation failed:
gcc-c++ needs courier-authlib-0.58-1.i386

OK, I said, I found that rpm and --as root-- installed it (rpm -ivh courier-authlib-0.58-1.i386.rpm)
then I ran again
sudo rpmbuild -ta courier-authlib-0.58.tar.bz2
the system response was the same.

What can it be?
Thanks in advance and maaaaaaaaaaaany congratulations for the site...

You got it....
I was sure I had already installed it, but I was wrong...
Now i'm goin' on, hoping not to have other "breaks"...

Thanks!
