[Dovecot] Problems with Sent folder

We are using dovecot-0.99.13-3.FC3; the users use IMAP. I have had several of these today where the user cannot write to their Sent folder on the server. The users do own everything in their home dir:

[root@jidmail lcrdjav]# file Sent Sent: ISO-8859 HTML document text

What is up with the HTML, I am not used to seeing this in any of the IMAP folders ?
