I have a XPS M1330. I bought a 5520 WWAN for it. It works great
except for one little thing. My email doesn't work with it. It works
fine with the old Averatec and Sierra 875. I am not sure the problem
isn't in Vista or the computer itself. I was in a Motel with wifi last
night and had the same problem. It works fine on my home DSL and
wifi. I set up the email in windows mail. I was led to believe it
was the same as outlook express that is on the old machine. Any help
will be appreciated .
I have the XPS M1330 and am currently looking at getting the 5520 WWAN card.
The network supplier you are using to connect to the internet has probably blocked for other outgoing servers (SMTP) than their own. This is a pretty normal occurrence nowadays and they do it to limit the amount of spam that's being sent through their networks.
I use Thunderbird as my email client and have set up multiple outgoing servers. One for work, one for home, one for various wifi-spots etc. I use an adon to change smtp when sending emails. It's called "Buttons!" and is included as an option for the outgoing mail view.
