[X4U] Re:Mail problem

[Michel Treisman]

Hi,
I have a problem with Mail.app misclassifying junk and not junk.  I get 
email alerts, which I want to go into my Inbox. I have regularly 
classified them as 'Not Junk', but half the time, Mail  puts them in 
the junk-mail box.
This happens even though Mail  classifies them as ‘not junk’.
I have tried putting the source address in my address book, and I have 
created a Rule to put mail with the alerts source address in my 
inbox.  But the mail still ends up in the junk-mail box.

At this point I thought the preferences might be corrupted,  I should 
try trashing the preference  com.apple.mail.plist.

So I removed com.apple.mail.plist from User/Library/Preferences. Next 
time Mail started up I re-entered all my preferences into 
Mail/Preferences, just as they had been before. This worked fine for 
two POP accounts I have, but not for my IMAP account. I can no longer 
read email sent to that account.

What seems to happen is that trashing the preferences and re-entering 
them  seems to create a new folder in User/Library/Mail    called 
IMAP-(my name)@(server). This sits side by side with the old folder 
that is already there, also called IMAP-(my name)@(server) which has 
all my old mail in it. 

Emails I send to myself at the IMAP account now seem to go to the Inbox 
in the old folder, but Mail.app (I’m guessing) looks for mail in the 
Inbox in the new IMAP folder and doesn’t find any.
I removed the new folder called IMAP-(my name)@(server), and restored 
com.apple.mail.plist from backup. So now I get my mail again,  but I 
still have the problem of the email alerts getting misclassified.
Any suggestions?
