I have a POP3 email account. I have a laptop and receiving email is no problem for me where ever I go. However sending email is. When I send my email from home I have no problems. But when I go to a friend's house and use their connection it fails to connect to the SMTP server. From this I can only guess two things. Either my friend has some port blocked that SMTP needs or my connection needs to be through my ISP for SMTP to work. The blocked port makes more sense to me on it's face however I doubt all my friends have this port blocked I noticed this same problem when I had two ISP at home a long time ago. I had AOL and Netzero. When receiving POP3 mail I had no problems. However sending mail from my @netzero.com account was only possible when I connected to netzero. Can someone clear this up for me?
