Help Please!! Can't receive email - windows vista

[stan in Oxfordshire]

Please help!! We have our new windows vista lap top with two email accounts
set up, we can receive mail but can not send mail. Our internet connection
is by a T Mobile usb stick if this makes any differance? This error code
appears for both accounts when we try to send .

As a general rule, the SMTP server you use must belong to the same
owner as the network supplying your connection to the Internet.

Contact T-mobile and ask them if they have an SMTP server you can use.
