Some of you have probably seen this one, but since I'm creating a lot of templates these days, I just had to post it in order to give myself some relief. Anyway, this timetable is really a must-see for everyone who even think of getting into web design/development. It's hilarious, but true.

SMTP is the acronym for “Simple Mail Transfer Protocol”, which is the protocol used for sending email. Anyone who has ever sent an email has used the SMTP protocol behind the scenes. “Open mail relaying” is when an SMTP server is configured in such a way that it lets anyone send email through it. The problem people have now is that open mail relaying is a thing of the past – it is now much more difficult to find an SMTP server that will work for you. An SMTP relaying problem arises when you try to send an email through an SMTP server and find that you cannot, typically with an error message reading “relaying mail to is not allowed”.
