I have a new user who is using Outlook Express with POP and seems to be having a problem downloading messages with attachments. Watching the logs it starts to download and then disconnects. When I use squirrelmail which is IMAP it all looks good so it's not a corrupt mailbox.

I'm running Beta8 and using MBOX files. The problem seems to be related to POP and/or Outlook. Has anyone run into this before?
