can't send email via exchange 2003 server RRS feed

  • Question

  • Hi guys

    In my work please we use school program and every client need to send email.

    We have exchange 2003 , so client was able to send email to anyone via exchange 2003 server with our domain ( of course I have already set it up before ) .

    Anyway recently we can't send email via exchange 2003, I checked all setting , it seems everything is ok . I  used outlook 2007 , no luck, I used telnet no luck. But the strange things when I create .txt file  like below

    From: myname@mydomain.com
    To: someone@somedomain.com
    Subject: testing

    This is the test message body.

    and drop this text file in  X:\Program Files\Exchsrvr\Mailroot\vsi 1\PickUp  ,  it works.

    Could you please give me any idea why I can't used when I use outlook or telnet .

    Thanks

  • If you want to send email externally via SMTP (rather than MAPI) then you are going to have to allow relaying.

    You have two options for relaying in Exchange.

    1. By IP address. That allows anything in a subnet to relay. Not recommended as it isn't secure.

    2. By authentication. This is allowed by default in Exchange and requires a username and password to send email. However that option maybe disabled because it can be abused - spammers will attack the Administrator account to try and use the server as a relay.

    Secure it thus:

    The text file in pickup works because that isn't relaying.

  • hi,

    How about message tracking log say? Message tracking log:http://www.msexchange.org/tutorials/Exchange-2003-Message-Tracking-Logging.html

    Since you have test telnet, what's the result? Please post.

    hope can help you

    thanks,
