I have iredmail installed and I just created a new subdomein for a domain. In my existing Vhost I added the subdomain.
The problem I have is that he always redirects to roundcube and makes the link https://b2b.domain.com/mail

How can I fix this?

<VirtualHost *:80>
ServerName b2b.domain.com
DocumentRoot /var/www/domain.com/public_html/
