External mail dirs for Dovecot

[pmcewan]

I've installed Ubuntu 8.04 as a mail server, and it's working very well. However, I need to put the mail directories on an external Windows file server. When I try to do this by moving the mail root to the external file server using samba and symbolic links, it gives a lot of errors in Dovecot.log. The errors are below, but is there another to do this? Can the email be pushed into MySQL instead somehow? The Windows share has all rights granted to everybody for now. Thanks -- Paul
