SMTP problem with sending email to external internet address

SMTP problem with sending email to external internet address

Post by Lim C. L » Thu, 02 Mar 2000 04:00:00



Hello,

I am writing a program to send email to external internet address but it
does not work.
But it works if I sent from one mailbox internet address to another.
Anybody has any ideas what's wrong ?

Essentially, this is how my program works :
I telnet to my Exchange Server Port 25 :

HELO
250 OK

Exchange mailbox)
250 OK

250 OK
DATA
354 Send Data. End with CRLF.CRLF
test 1 2 3

250 OK

However, when I checked my hotmail account there is no incoming email.
And there is no sent mail in my Sent Item folder in the mailbox.

Please help.

Best Regard,
Lim Chuan Lip.

There wouldn't be mail in the sent items folder because the mail
wasn't sent from your mailbox. Also your example doesn't end with
CRLF.CRLF. If you manually telnet to the Exchange server and issue
these commands does it go through?

    Hotmail might also be rejecting the message because of its lack of RFC
822 headers (To:, From:, Subject:, Date:, and so forth).

I suspect that you do not have mail relay turned on in the IMS service.  Be
careful turning this on as it leaves you open to SPAMmers using your
service, you should use the advanced option to restrict by login or IP
address.

All of this is in the Routing tab of the IMS service configuration item in
Exchange server
