Dost ap jis address per email behj rahay ho wo domain exist nahi karta yani http://www.sco.gov.uk aur is per email bhi nahi ja sakti agar domain exist kerta hai tu email address jo aap ne nahi bataya wo configured na ho. google main search karo shayed aap ko email ya phone number mil jaye. Meray ilm k mutabiq ye waja ho sakti hai
