After 3 years of running perfectly, my mail program (mail 1.3.11 v622/624) stopped showing my mail. I have talked to my ISP and they say it isn't anything they did. I can access the mail through other POP programs but I can't get the new mail to appear using the Mac mail. I have not changed any settings on my computer, a G4 running 10.3.9. Can I just download a new Mac mail program? I only see the ones for Tiger, which I'm not using. Any suggestions would be appreciated. Thank you.
