We just got cable internet (wohoo!). Fast and wireless (PB G4 550Mhz, 10.3.1). However, our provider blocks all but it's own ISP from sending mail, "forcing" me to use their smtp server. This isn't a big deal, as I can easily select a different server when a piece of mail fails to send. It is annoying, however. Is there some script, hack, or way to have mail.app - based on my network setting - to change which smtp servers to use? Can I create two sets of preferences, and swap them when I am at school/work, and then when I am at home? Because when I am at school/work, I doubt I can send my mail though my ISP's server. Thanks! PS - I am cross-posting this because it borders on both x-apps AND mobile computing.
