I don't know how many times I've travelled abroad, sat down to handle my personal and business email using my simple Outlook Express email client, only to find that for some reason I can RECEIVE email OK but I can't SEND email. This annoying problem forced me to resort to web mail, such as Gmail, which I find slow, cumbersome and non intuitive. Well, finally on a new trip I had time to sit down and try to find out once and for all how to solve this annoying problem. And solve I did, but it took me 10 days of messing around which this article will save you from.
