Virtual E-Mail Problem

[amurray]

Hey All,
I just set up a fresh install of Fedora Core 5 [howtoforge - perfect fedora core 5 setup], and installed ISPConfig. I am now having the following problem, which I am sure is just a newbie configuration problem. I created a new client [MyHBN], and created a new website linked to that client [myhbn]. The host for both client and website is 'www' and the domain is 'myhbn.com'. I also created a codomain with an empty host field and the domain as 'myhbn.com'.

Now the problem I am having is that when I add a user I am getting:

username@www.myhbn.com *rather than* username@myhbn.com

I have checked the /etc/postfix/virtusertable file and see the following (4) entries for the user :

ajmurray@www.myhbn.com myhbn.com_ajmurray
myhbn.com_ajmurray@www.myhbn.com myhbn.com_ajmurray
ajmurray@myhbn.com myhbn.com_ajmurray
myhbn.com_ajmurray@myhbn.com myhbn.com_ajmurray

There are a whole lot of entries, and the only one that should really be there is the third line (ajmurray@myhbn.com myhbn.com_ajmurray)

I have installed both UebiMiau and RoundCube.

RoundCube:
I log in with myhbn.com_ajmurray as the username, and I try to compose a message and it appears that it is coming from:

myhbn.com_ajmurray <ajmurray@www.myhbn.com>

-- I would like it to say --

Aaron Murray <ajmurray@myhbn.com>

UebiMiau:
I am unable to log in at all. I have tried all possible usernames (in the email field) with no luck:

ajmurray@www.myhbn.com
myhbn.com_ajmurray@www.myhbn.com
ajmurray@myhbn.com
myhbn.com_ajmurray@myhbn.com
myhbn.com_ajmurray

I appreciate any help on any of the above problems.

Thank you
Aaron Murray
