Well, for starters, I don't think you should be using ActiveSync.

You can use IMAP or POP, your preference.
POP can be configured to download emaild, but leave them on the server, so that they will still download to the PC, even if you delete them from the phone.
IMAP will keep all clients in sync, so that mail deleted from one will be reflected on the other. It's worth checking what your main PC at work is configured to use I suppose.

So select new account -> POP/IMAP, then fill in the fields accordingly, choosing the rigt ones depending on whether you want to use SSL or not:

For POP3, SSL

email address:- <your email>
username:- dan+danstengineering.co.uk
password:- <password>
POP Server:- sh3.valcato.com
Security Type:- SSL
Port:-<Not sure, default of 995?>

'Next' - Hopefully it will validate your account, and move onto the outgoing setup

Check 'Login required'
username:- dan+danstengineering.co.uk
password:- <password>
SMTP Server:- sh3.valcato.com
Security Type:- SSL
Port:-465

That's probably not 100%, but should get you most of the way there. You might need to see what port is required for your incoming (POP) server.

Also, you might find that you won't be able to send mail unless you are on your work WiFi, most SMTP servers don't allow relaying - Sending from an IP address that isn't recognised as 'Theirs'. My ISP email account won't work unless I'm at home, so I had to switch to using T-Mobile's smtp server which allows me to send, but only on a mobile data connection, not WiFi! So I use Gmail now, I can send from anywhere...

Great, glad you sorted it.
