Sending email from third party smtp servers

[Ed Clark]

As a developer, not using MAPI - how would one send email
through a smtp server other than microsofts'? It appears
that when dialed in through MSN Internet Access -
Microsoft prevents one from telneting to third party smtp
servers. (ex. smtp.mail.yahoo.com)
(Though support level One - insists this provision does
not exist)
After much investigation I did find an article under the
Knowledge Base which reads:
"...if you created your MSN account after 12/15/2000, you
will not be able to send e-mail from an additional account
while connected to MSN. You can only send email from your
MSN e-mail account while connected to MSN." (article #Q293)
With this restriction in place - it appears that Microsoft
wants only Microsoft Applications or those that conform to
MAPI - the ability to send email through MSN.
However, one may telnet or receive email from third party
pop3 servers either from a Microsoft Application - or a
third party app.

Is there an explanation for this?

Thanks for anyones' reply.

This is very possible -- they want you to use their mail server. Solution:
find an ISP that doesn't restrict this.

Yup, exactly.

Now I'm confused -- when you say 'a third party app', do you mean that if
you use (say) Eudora and point it at Yahoo's pop3 server, it can connect and
send/recieve mail, but if you just try and telnet to there, you can't even
make the initial connection? There shouldn't be any difference between the
two in terms of connecting.

There may also be differences between restrictions on pop3 and smtp access;
they might not care about you reading mail from other places, but want to
ensure that any mail you _send_ goes through them (so they can add adverts
at the bottom or whatever).
