I've used Virtualmin and Horde for my personal email service. Virtualmin does a very good job configuring Dovecot, Spamassassin, Postfix, DNS, Apache/Nginx, etc and Horde is a very good web client for email, contacts, calaendar etc.
I'm happy Virtualmin is working well for you. We've been working quite a bit lately on making Usermin nicer as a mail client, as well (not to discourage use of Horde or others; we also provide easy installers for Roundcube, SquirrelMail, and a couple of other webmail clients...some are even free in the GPL version).
We're planning a major new release as soon as I finish the new website and we get some integration work done, that completely overhauls the UI in Virtualmin/Webmin and Usermin, which I think is the biggest issue with Usermin for webmail and one of the reasons I don't even use Usermin heavily for mail (I use Thunderbird on my laptop and GMail on my phone).
How many years - the domain appears to have only been developed in 2012?
FWIW they also appear to be breaking European law by not displaying their trading/registered offices address on their website.
Crazydomains.co.uk seems to be a non-registered trading name (ie it's not lodged with Companies House) for DreamScape Networks FZ-LLC. That company is apparently based in UAE?

I would definitely recommend using Virtualmin, its a hosting control panel that can control mail/websites/dns in one via a simple control panel.
All works like Plesk, but without breaking everything.
They've got a script that sets up dovecot, postfix, apache, bind, clamav, spamassassin, Mysql, and loads of other hosting software and then you configure every thing via a web interface.
I use a catchall and give different email addresses to everyone. I've received 3 spam emails in the past month to my dropbox account, but they aren't the only ones with problems, for example the following are the number of spams for various sites:
* 2 emails Foursquare
* 6 emails Groupon
* 6 emails Rackspace
* 25+ emails Ticketmaster
* 50+ Absolute Radio (UK Radio station)
Absolute Radio was hacked, not sure about the others.
