Reply sends to Administrator, Not the previous sender

When one of our Macintosh users sends a reply to most e-mails, it will send the e-mail to one of our previous administrators rather than the person that he was trying to reply to. Any ideas what could be wrong?

Thanks,

Russ

If this is from Internal addresses only then check the “Mailfile Owner” in the Preferences dialog of the original senders mail file.
