We are running sendmail mail server on Red Hat Linux 7.2 and using Netscape Mail and News group as mail client. Recently, I got a strange problem with one user - When I created the mail account on Netscape, he can access mail in some of the folders such as inbox but cann't access many folders such as Sent, Trash etc ...and getting message - "The current command doesn't succeed. The Mail Server responded: SELECT failed. Cann't open mailbox Sent; no such mailbox".
However, he is also having the same mail account with identical settings on his laptop where he can access all these folders.
I tried creating his account on different machines but get the same problem.
Urgent Help is needed.
