is there an easy way to delete duplicates in mail 5.0?

[Epiphron]

I've had this issue before the update, but it's now more apparent. Whenever I get an email, apple mail puts one in my "all mail" inbox and another in my regular account inbox. Anyone else have this issue?

Do you happen to use Mail with a gmail account ?

Duplicates associated with gmail?

I also have two to four duplicates per email. I have added my gmail account to Mail 5.0, so I assume that's the problem, but I haven't figured out how to fix it.

I have a special sound associated with emails from my daughter, and when she emails me I hear the special sound plus the regular notification sound. Hope someone knows how to fix this.

Clarification: Actually, what I meant to say is that the two separate notification sounds indicate the message is being placed in the mailbox twice. This isn't what I hope to fix, as it appears from the previous paragraph. What I'd like to prevent/fix is the problem of the numerous duplicates in Mail 5.0 under Lion.
