I have a Mac Book Pro and recently had my home broadband upgraded to BT Infinity. Prior to this upgrade sending emails via my Mac mail was working perfectly. Since the new installation I could no send any external emails using the or smtp outgoing servers. was ok.? very strange.


So when I connected the same macbook to other wireless connections it would work perfectly.???


So after many hours wasted messing around, I managed to get the right person at the right time via BT helpline in the UK not India. (India helpine just say "we are not trained in Apple".


So the very polite man from UK Helpline provided me with the solution.



GO TO > Apple Icon top left > System Preferences > Network > Wireless >

Select your wireless connection > Click Advanced lower right on popup

Select DNS tab

Click on the + under DNS left pane and type the following :-

Click Apply



I hope this helps someone, as I know how painful these types of issues can be.


MacBook Pro, Mac OS X (10.7.5)
