Sending mail on WIFI networks

[Sanjay Punjab]

I have noticed that many WIFI networks I use around town block e-mail
messages I send. I get the following error.


Send e-mail message: The specified server was found, but there was no
response from the server. Please veirfy that the port and SSL
information is correct. To access these settings close this dialog,
then click more settings and click on the advanced tab


After doing some troubleshooting and research I found out that some
ISPs block any outgoing e-mail that uses SMTP servers othere than
there own.
Does anyone know a way around this problem?
Thanks

About the only way around it would be webmail, should the email system
you're trying to use offer that. If the ISP you're connected to has port 25
blocked, you're only other option is to use the SMTP server owned by this
ISP.

Unless you reconfigured your pop server address, when you try to send email,
you should be contacting your ISP's server directly - even if you're at a
public wifi hostspot. The standard problem is that your pop server refuses
to accept the connection, because your IP address is not in a subnet
exported by your ISP.

Usually you can receive mail from the smtp server, you just can't connect to
the pop server to send email. The purpose is to prevent someone who may have
stolen your auhentication information from using your email account to
generate spam.

One way around this is to get a web-based email account. You can always send
email from a web page, once you've authenticated.

Small nit-pik... this is backwards. You connect to an SMTP to send mail and
a POP server to receive mail.

Oops. Yes, I got these backwards. Thanks.

The problem probably isn't that the ISP is blocking SMTP traffic to any
server other than their own. It's more likely that the SMTP server that
you're trying to use is refusing your connection because it's originating
from an address that's not part of their network. If you know the name (or
address) of the SMTP belonging to the ISP that you're going through, use it;
it won't care that your email address is foreign.

Another possibility: if your email is hosted as part of your own domain,
then you may be able to configure your account to accept SMTP connections
from foreign networks.

I believe it. I would.

I get the following error.

Do you know who is originating this error? I'll guess it's your email
client because it can't connect.

This is to prevent their networks from being used by spammers.

There are four ways around this problem.
1) Use the ISPs mail server as your outbound relay. Setting this depends on
your client, but somewhere it will ask for "SMTP host". Set this to whatever
the ISP wants.
2) If you're running your own mail server, you can run an SMTP server on
a non-standard port. Please make sure you use something like SMTP AUTH
to make sure this machine doesn't become an open relay.
3) Use a protocol other than SMTP to send your email to the server. Some
clients allow you to submit messages for sending through the POP or IMAP
protocol.
4) Don't send email until you get back to your home network.

Pick whichever one works for you. If you don't know how to accomplish
these (specifically #2), then cross it off and go to another one. #1
is probably the easiest to satisfy.

Another solution would be to run an SMTP agent on your computer that
delivers your email directly rather than using your ISP's SMTP server.
There are many free SMTP agents available for download, a quick Google
search should find you a few.

Get a free email account from
softhome.net
You can then use port 25000 instead of the blocked port 25.

For somebody sending email from Internet cafe connections, that is an
impractical solution. Unless he has another computer at a fixed location
that he can leave on 24/7.

If I have understand your question, you are using something like an Internet
cafe connection to try and send email. Are you using the SMTP server of the
provider of the cafe's connection, or your own provider's SMTP server? If
you are trying to connect to any SMTP server, other than the one for the
Internet connection provider of that cafe, you probably won't be allowed to
connect.

One idea is to see if the SMTP server you are trying to use can be
configured for SMTP AUTH, or something similar. If your SMTP server allows
SMTP AUTH, it won't care about your actual Internet connection. However, you
still may run into Internet cafes whose provider blocks port 25 out; or even
find that the cafe, itself, blocks port 25 out. In the form case, use their
SMTP server, in the latter case, you may have to find an alternative means
of sending email. There are some services which allow authorized SMTP
connections on non-standard ports; or you can use Web mail.

Install smtp on your win2k or xp box, and use your own ip address (or
"localhost") for the outbound mail server. Keeps me in good shape wherever
I go.

An MSFT MTA on a computer connected directly to the Internet? The spammers
must be having fun with your computer.

How does the smpt server then forward the email if inbound/outbound
port25 traffic is blocked? Please provide more details.
