The new feature of email enabled document libraries in SharePoint 3 is great, but I recently experienced problems with getting a new copy of the mail every five/ten minutes. After a bit of error searching, I found that it was due to the fact that SharePoint didn’t have delete access rights to the “drop” folder in the c:inetpubmailroot directory, hence after sharepoint has read the mail, it can’t delete it. The next time sharepoint polls the directory, it will find the same mail and add it again, and again, and again… so just make sure the access rights are right.
