Same old date always appears on e-mails I reply to

Question

When I receive an e-mail, the correct time and date are on it. But when I post a reply to that e-mail, it always lists June 15, 2009 as the date I received the e-mail I'm replying to -- i.e. "On June 15, 2009, at 10:40 a.m., so and so wrote...." -- beneath my reply. How can I correct this?

Answer 1

I am not at a computer where I have my AOL setup -- I will get back to you later when I return home.
As for the date issue, have you ever removed the com.apple.mail.plist file in your attempts?
To further test, create a New User Account, and as that New User try to set up at least one account -- if you were to set up a POP, then select to leave messages on the server. If not familiar with setting up a New User Account, see:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
This will be a useful test to now check this behavior in another User Account, and of course is not meant to suggest a permanent switch to the New User Account, but rather a test of the Mail application outside of your normal User Account. Later, in the normal User Account, removing the plist file or account folder may be beneficial.
