I just upgraded my mini from Tiger to 10.5.6, and at first I thought mail was refusing to go online because there are triangles with exclamation points inside next to both of my email accounts (they are gmail, btw). Yet I can send and receive emails. So then I though the exclamation points must mean something other than not being online, but when I clicked on one I got a message that said "Unable to connect, and gave me a blue "Take online" button. Clicking on this button did not make the exclamation point/triangles go away. So apparently Mail thinks it's offline even though it's obviously online. I tried the "Mailupdate10.5.6.dmg" file from Apple, but that didn't fix this issue. Anyone know how I can convince Mail that it's online?
