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
