    Default ose 5.07 w/mmdf's smtp adds junk

    After recent upgrade to Openserver 5.07, all security and patches to-date,
    with MMDF as MTA, have come across the following problem.

    PC's in network send email through 507 box, which channels it out over net.

    the SMTP process, however, is adding the pc name to the host-name, after
    which some upstream SMTP server is rejecting it because of a malformed
    host-name header - apparently, the PC's name is getting pre-pended to the


    for example,
    Your message cannot be delivered to the following recipients:

    Recipient address: tech1:com
    Reason: Illegal host/domain name found

    anyone know where this is happening and how to stop it?

    That's a strange message. MMDF will in some cases generate a source route for

    address. This behavior can in some cases be worked around - see for example
    http://groups.google.com/groups?selm=3c992631%240%2422477%248eec23a%40newsr eader.tycho.net

    But, there is currently no way of just turning it off. Correctly configured
    MTAs don't have a problem with such addresses, but it wouldn't be surprising
    to find some with anti-spam hacks applied that did. I'm working on an MMDF
    supplement in which source routes are no longer added by default, but it'll
    be a while before it's available.

    i believe that *IS* the return address mmdf is constructing.
    so you are saying i should put something like
    tech1:com: magnatechonline.com
    in the root.dom file?

    i probably should have posted more of the error as i think i posted the
    return failure - not the original delivery failure, which is more like:

    Remote host responded: 550ification failed for
    <marena%magnatechonline.comtech1>

     

    my guess is it is an anti-spam thing that is trying to verify validity of
    sender address.

    You need to map the source hostname that MMDF sees to the hostname the user is
    supplying in the return address, so that MMDF will believe a source route isn't
    needed:

    tech1: magnatechonline.com
