Outlook Express won't send

By dlauch

  1. I am running Outlook Express 6 and out of the blue it won't send e-mail but it receives e-mail. [I get the error : The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was XXXXXXXXX'. Subject 'Test', Account: 'mailhost.spf.ameritech.net', Server: 'mailhost.spf.ameritech.net', Protocol: SMTP, Server Response: '550 [PERMFAIL] hotmail.com requires valid sender domain', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79.]

    I get this error no mater who I send an e-mail too (not just hotmail). I have the same account set up on a different computer with all the same account info., servers, ports, passwords, authentication, etc. and I can send e-mail from that machine. So the problem must reside with this computer. I have done a system restore to a date previous to my last successful e-mail sent and this changed nothing. I have disabled my windows firewall and I cannot send as well.

    Any suggestions?

    Baffled.

    see this
    and this

    The Outlook smtp address mailhost.spf.ameritech.net does not belong to YOUR ISP and thus attempting to use
    mailhost.spf.ameritech.net creates what is known as an
    Open Relay request -- correctly denied to stop as much spam as possible.

    jobeard,

    I don't understand what you mean that mailhost.spf.ameritech.net does not belong to my ISP? It is the server assigned to me. It's a ppop account that requires an account name and password to sign on. I have two other computers in the house with Outlook Express that I am able to send e-mail from over that server.

    Confused?

    your confuse -- and now I am too.

    The error message is from the smtp server itself and the 550 code means what I reported. your settings are in question.

    when I tried to ping it, notice what happens to the name:
    Code:
    $ ping mailhost.[B]spf[/B].ameritech.net
    
    Pinging mailhost.[COLOR="Red"]chi[/COLOR].ameritech.net
    
    If mailhost.spf.ameritech.net is truly your ISP smtp server, then
    you need to call them to help you with your outgoing email settings.

    More Confused

    I have now also pinged mailhost.spf.ameritech.net from one of my computers that I successfully can send e-mail from. I also get the return from mailhost.chi.ameritech.net. All three of my computers running Outlook Express have the account set up exactly the same for the outgoing mail server. Two of the three can send e-mail, my office computer gets the error message posted.

    ???

    Is it using the same Router/modem/ISP as the others?

    jobeard,

    I have a dsl modem with a Belkin wireless router connected to it. One computer is connected to the router via ethernet cable, my office computer has a usb wireless adapter, and my laptop has a built-in wireless card. I can send e-mail from my laptop and from the compter connected via the ethernet cable, not from my office computer.

    dlauch: Are you sure you are connecting to your WiFi router and not some other in the neighborhood?
    How can you tell? If you would acess the Dlink router using a cabled connection, you could login and see the SSID being used. It is simple to
    change and would allow you to be absolutely sure that it's yours that is being used.
    If you accidently access some other WiFi, then you would be going thru THEIR ISP and thus the 550 error would be expected :(

    hum; that's just a rewording of what was already posted above.
    sorry, not so. I use a local proxy system all the time and the 550 error has nothing to due with the proxy or an A/V scan of outgoing email. It is from the smtp server as noted above.

    jobeard,

    Yes I am just connected to my WiFi. I can see two other networks in the neighborhood but all are secure. I log onto my own with a password.

    As a test, I decided to set up an additional identity in Outlook Express to create another account where I entered all the exact account information, servers, ports passwords etc. as my primary account. Guess what? I was able to send e-mail from that account. So something is corrupted in my primary account, even though all the account settings are exactly the same as all these other accounts that I can send e-mail from. I will create a new mail account and then delete the old one. The biggest hassle will be deleting over 1000 e-mails that will be download from my server and mixed with the e-mails I still have in my inbox.

    Thanks for your input. Still don't know what has ultimately happened but have come up with a work-around to the problem.

    jobeard, didn't mean to double up on you. I did however leave the link to my source of Inisideoe.
