said by yabos:What if your provider's SMTP server(s) is/are overloaded by the weekly Windoze worm? Then you are forced to wait for their overloaded server to deliver your email.
The whole point of widespread port 25 blocking is so that there isn't excess traffic created by worms. -- Don't have it?!? Demand it!!! The Anime Network »www.theanimenetwork.com
That only works when the worm has it's own SMTP server. Most only use Outlook to send via the SMTP server set up in that program, which is almost always the ISP's server. Thus, it becomes overloaded.
