ASP.NET SMTP mail never received

[ibiza]

Hi all,

I am trying to use the System.Net.Mail class for the first time, with
ASP.NET 2.0.

I setup everything according to
http://www.codeproject.com/aspnet/EasySMTP_package.asp, which gives me
a working environment for sending mails.

I am sure the code is correct, there are no errors and everything seems
to work fine. However, I never receive the email. I've done some
research before posting this, and I suspect it is never sent because I
use a totally random email for the Msg.From Attribute, which may be
wrong. I am under Windows XP, IIS 6.0, and I would like to know how am
I supposed to know what valid email can I put in the From ?? Is there a
way to add mail (forward only) addresses from which we can effectively
send emails, somewhere in IIS or anywhere else? How am I supposed to
know what email to use in the From, if I simply sent it from localhost
(no domain or anything, just my own computer)?

Any help on this would be much appreciated,
thanks in advance!

A quick check would be to see if you're dropping your email messages at the
SMTP relay.

%systemdrive%\i netpub\mailroot \drop
%systemdrive%\i netpub\mailroot \badmail
%systemdrive%\i netpub\mailroot \queue

That'd help to narrow out if it's the code (if your message is being generated
and packaged OK) or the SMTP on your web server.

In the from field, it depends on your SMTP server. Our Exchange servers
are locked down and require you to have the same domain, so we use donotreply@{
our domain here }.com or something similar. You should be able to use your
own email address.

If you're curious about your code, have you tried using breakpoints in your
code and stepping through to make sure it hits each step?

Thanks for quick reply :)

I've checked in all subfolders in %systemdrive%\i netpub\mailroot ,
nothing there. Also, I've enabled tracing in IIS, to see if it would
give some hints, here's what it has generated when sending mail :
23:01:24 192.168.0.100 EHLO - 250
23:01:24 192.168.0.100 MAIL - 250
23:01:24 192.168.0.100 RCPT - 550
23:01:24 192.168.0.100 QUIT - 0

I haven't a clue of what that means...

For the From field, I am really no expert in terms of domains and all,
so that's why I suspect the problem is there...you say you use your
domain, but what's mine if I simply want to send an email from a
localhost IIS server, not attached to any domain? I tried to send from
my email, as you said, (which is a gmail.com address), and it still
doesn't send..

I stepped into my code line by line (it isn't that long), and
everything is executed normally, even the
MailObj.Send(Ms g)

So, I really think it that 'domain' problem :\

thanks again!

In addition to the previous post

(inetpub/mail stuff)

you also want to make sure you specifying the correct "authentication ".

Try different email (recipient) combo's , because sometimes something like
hotmail will block an incoming email. That's probably not the issue, but I
mention it anyways.

well, all setup in IIS should be fine.

Do you mean 'anonymous' as authentication (in IIS)?

No, the end smtp server sometimes need authentication.

Read the blog... will show more.
sometimes, like with dialup, you use "none" authentication.

sometimes , they want you to at least pass them your account id, and a
password.
(basic)

sometimes, they want a password, username and to use SSL (ssl
authentication)

It mimicks all the smtp settings you'd find under Outlook Express ...

I made it to put the message in the
%systemdrive%\i netpub\mailroot \queue folder, but now, I can't tell it
is still in queue...I made the change to the Msg.To field ->
'donotreply@ibi za'
where ibiza is my domain name (computer name)

Any ideas why it's stocked in queue now?

re:

'donotreply@ibi za'
where ibiza is my domain name (computer name)

How do you expect a message to be delivered if it doesn't have a valid "To" address ?

emails.
