    Default Need help using mail

    I need to send messages between two systems which change IP on a random
    basis (Qwest DSL re-assigns the IPs every few weeks). I can query the
    router from the local machines on each installation to get the IP assigned
    by Qwest and I want the scripts to send an email to a mail server on my
    hosted domain so that I have a fixed mail target to pass the info. Problem
    is that the remote smtp is blacklisting the IPs assigned to my routers. Is
    there a workaround to force the source IP on the email to a known
    acceptable address?

    Considered signing up for one of the dynamic DNS services? If they work
    on Linux they could help. Faking the IP address when sending it may be
    tricky; you would probably have better luck finding a new relay for your
    mail. Perhaps instead look into the dozens of sites that will send you
    test messages via a web browser. Use curl or wget to send the browser
    request crafted to your liking so you get a text message. Put in your
    e-mail address as the sender and some of them may even CC you with the
    message details.

    It's a long shot, perhaps, but you could also just pay a few extra dollars
    for a static IP address.

    Good luck.

    And so it should too. Malware infected zombie machines are the bane of everybody for relaying spam. The IP address of the sender can't be faked. Banning connections from dynamic IP ranges that have been declared as such by the ISPs or blacklisted is one of the more effective measures to stop spam from entering.

    Why aren't you using Qwest's mail relays to send outgoing email?

    Why some of us having balding foreheads: Now why didn't I think of that???

    Oops - Qwest stikes again. They provide only the DSL link and contract MSN
    for IP services. Getting to the mail server is proving to be a PITA.
    Strange - the mail sent from kmail or other clients gets thru the server I
    wanted to use just fine but a direct mail send gets trapped. My ignorance
    is showing here, I guess.

    Is there any way to use a command line link into kmail (or some other email
    client) to have it format and send a message? I'm with you on the spam
    security thing - that's why I haven't even messed with setting up a mail
    server here. ftp might just be a simpler approach anyway and I know that
    works.

    If it works for kmail there's no reason it couldn't be made to work for a script or a command line client. When you set up kmail you must have entered a SMTP relay that Qwest told you to. This is the relay host.
