The Desire...
After you have purchased a Pocket PC and you wan to use it with one e-mail
address to send and receive e-mail. So you go out and get an ISP account
and setup the e-mail. It works great through that one
provider. Then you say, well I really need dialup access so you
attempt to use the ISPs dialup service (if they have one) and try it
there. Finally you'll try services like GPRS wireless and try to
send and receive e-mail as well. Somewhere along the line you may
find that you cannot send e-mail with your ISP. This article
describes why this is occurring. I'll also give some ideas on how to
work around the problem.
Security - Preventing SPAM
Basically each e-mail server has security controls which prevent users
from sending e-mail that is not from their service. These controls
can include checking the IP address of the remote destination, asking the
user to authenticate to send e-mail (SPA), confirming the originating
e-mail domain name is the same as the ISPs. All of these functions
can prevent users from sending e-mail through SMTP (Simple Mail Transport
Protocol). Each ISP has different rules about what you can and can't
do so I suggest contacting the ISP and finding out what the rules are
before you get started with trying a new service.
Picking Up E-Mail
I have found that most POP3 e-mail servers allow users to receive e-mail
from any connection. So you
should be able to receive your e-mail via wireless, cable modem, ADSL and
dialup without problems.
Workarounds
The workarounds I have found so far include:
- Finding an ISP that allows you to send
e-mail through different services.
- Using web based e-mail like www.webbox.com
which access POP3 e-mail servers. I realize this is may
require more online time that people want.
- Setting up your own domain and using it
to send all your mail. You need to make sure you check with your
ISP to confirm that they allow you to send e-mail. One great
side benefit to this is that your e-mail address will no longer change
since you don't care what ISP you are using.
Conclusion
I created this article to explain why
users are unable to send e-mail using different ISPs.
