Thanks alot guys, Ill look into that.
Edit:
Found this on Skys mail config page
Should I use POP3 or IMAP?
If you're trying to decide between using POP3 and using IMAP, we recommend you use IMAP with Sky Email. POP3 is prone to losing messages or downloading the same messages multiple times, but IMAP synchronises your mail clients and your web-based Sky Email more effectively.
Thanks again, Ill report back in a few days.
