My ISP provides no SMTP service, just dial-up. Sending email via Mail.app with a .mac (I use only Yahoo! and .mac email) account works somewhat (after wrestling it a bit) and usually only for small messages.

Looks like if I want to keep this all free, I need to stay away from sending .mac mail with Mail.app - perhaps Mozilla's mail client will do a better job..

Yup, AT&T does that too. Just had to fix this for a customer. It is a PITA, although I can certainly understand why they do it.

Use mail.attbi.com for the outgoing SMTP server.
