For some unknown reason my mail.app has decided it does not want to send mail with attachments, it sends mail w/o attachments just fine. I deleted the user accounts and reentered them and they seemed ok but it is now doing the same thing. I am running 10.2.5 on a beige G3 that has been upgraded to 500Mhz, it is hard wired to a D-Link Router and cable modem with ISP being earthlink.net and it hasworked fine in the past. I know it is not a problem with my isp server since I can send mail with attachments from my lap top through the same service. The program had been working fine and I have not changed any settings, I double checked them against my iBook settings.
