[kde-freebsd] Kmail duplicating e-mail messages on IMAP server

[Joe Kraft]

I'm using KMail (v 1.13.5) which came with KDE 4.4.5 and FBSD 8.1.

I'm using an IMAP mailbox on Godaddy's mail server.  I'm having a weird 
issue I'm having trouble tracking down and looking for help to figure it 
out.  I see some similar things have happened before, but none seems like 
this.

Every time I check e-mail it duplicates the e-mail from one person. Always 
the same person.  Every time KMail checks my mailbox, it generates an 
additional mail item from this person.

It does not happen when using the web mail interface, when using Outlook 
2007 or when using my with Windows Mobile 6.1.  Only when checking mail from 
KMail.

I used the web mail interface and deleted all mail from this person.  
Everything worked fine for a day with no duplication problems.  I sent them 
an e-mail this morning to test things out and it's duplicating their 
messages.  I'm relatively confident it has something to do with their e-mail 
in particular.

I'm open to any suggestions... or requests for further information.
Joe.
