anyone know if there is a pop3 block on sky ?

i had pop3 access via outlook yesterday on this pc and today its not working on yahoo or uk2net pop3 email access.

interestingly pop3 sky email IS still working via outlook.

so i have outlook pop3 email for sky but yahoo and uk2net are blocked..

anyone else got this issue ? only just happened today by the look of it.

Friday 13th issue?

cheers for any replies !
