410<p>
411Before we set up our virtual mailhosting environment, we create a functional
412user under which the virtual mailboxes will be hosted. For clarity's sake we
413will call this <e>vmail</e>:
414</p>
415
416<pre caption="Adding the vmail user">
417# <i>adduser -d /home/vmail -s /bin/false -m vmail</i>
418</pre>
419
420<p>
421So now you've set up the vmail account. You can create multiple accounts if you
422want (to keep some structure in your set of virtual mail accounts). The user id,
423group id and home dirs are referenced in the MySQL tables.
424</p>
425
426<p>
427Next to the user account we also need to create the location where the mailboxes
428will reside:

628At this point you may be wondering what user and directory to use for virtual
629mail users, and rightly so. Let's set that up.

631
632<pre caption="Adding the vmail user">
633# <i>adduser -d /home/vmail -s /bin/false vmail</i>
634# <i>uid=`cat /etc/passwd | grep vmail | cut -f 3 -d :`</i>

636# <i>mkdir /home/vmail</i>
637# <i>chown vmail: /home/vmail</i>
638</pre>
639
640<p>
641So now when you're setting up vmail accounts, use the vmail uid, gid, and
642homedir. When you're setting up local accounts, use that users uid, gid, and
643homedir. We've been meaning to create a php admin page for this setup but
644haven't gotten around to it yet, as phpmyadmin generally works fine for us.
