Hello, I am needing some help. I have been using WML 2012 absolutely fine from my Sky/ yahoo email account into WML 2012. Yesterday I got the message below and have not been able to send emails from this account.

I can receive emails ok but i can not send any mail. I have called Sky support and they say no problems from their side. I have checked my pop and smtp settings and all looks good. I'm pulling my hair out as i can't see to get a solution. Can anyone assist me please. Best wishes, Nicola
