    Hi J Tucker
    In lieu to you demise in sending email
    and getting errors 554.0.0.0 Service unavailable Sometimes the receiving ISP
    will detect attachments with syntax words as fun, download, pictures, photos, etc
    and suspect them as viruses and/or spam. Sometimes you can jump over the
    problem by sending the message in ASCII format or just remove the picture and
    give the link to the picture in the message
    EXAMPLE: photo: ref http://www.angelfire.com/droid/aisvnazron/images/Logo-SpecialReport.jpg
    Even though the pictures isn't present, the link is available so the receiver can see it.
    Also certain configuration will trigger the spam filters and reject your message.
    AOL is notorious for this action and use certain keywords which will reject your
    message and as a generic message bounce your message back as " Service Unavailable "
    because it found something in the message it recognizes as
    POSSIBLE spam or unusual. If you know HTML coding, you can send the entire
    message as " <STYLE> text< /STYLE> " with the links to exclude the HTTP protocol. i.e. <script=TEXT

    Regards

    Jim
