Do you mean sending email from your Sky email account?
I don't use Sky email service (I learned my lesson from relying on ISP email accounts as when you jump ship and leave an ISP, you gotta go through the hassle of switching email addresses and stuff - anywhos) - but my Google Mail account which I've set up in Outlook has been timing out a lot more often that usual; in fact, it has never given me problems until a couple of days now, don't know if this is to so with internet or google itself!
