I have windows xp on my pc. I have software that I use with my digital camera to send pictures in my email. When TRYING to send these pictures I get an error message something to the effect that message not sent pop3/smtp error. What is it and how do I fix thanks for the help...Does your REGULAR e-mail work OK? Are you on dialup or cable/DSL? Who is your ISP? What kind of software? Does it have a name? How big are these image files? More info is always helpful...ok i take it you dont use OUTLOOK express or microsoft outlook ( prolly a good thing ).
ok for one when your downloading photos from your camera to your pc dont select the option to email them. this will only confuse you. just select the option to copy or move the photos to your pc. Here once they are on your pc in a FOLDER you created for them. open your email up and create a new email message , then use the feature to attach files and attach what ever photos or files to the email you want.

Seeing you dont understand these basic internet PROTOCOLS i aint going into them too much but they are just protocols for use on the internet in the use of sending and recieving email. pop3 for sending email and smtp for recieving ,, When you configure outlook express the first time you are asked to provide these things which your ISP can provide you with. ie. the names of the pop3 and smtp servers that your ISP uses for providing email.

I hope this helps.
