Thanks Skaero for your reply.
I had a look to the webpage that you suggested me.
I've changed some values, but I can not see any dirrerence...
I've setup:
pagesize = 20
preview_pane = TRUE
enable_caching = FALSE (since the IMAP connection is on the same machine)
imap_auth_type = "plain"
smtp_auth_type = 'PLAIN'
Am I wrong in something?
I was also reading how to setup the imap proxy, and at the end I setup it, but of course it's exatly the same (since the IMAP connection is on the same machine, so che IMAP proxy have just no sense).
Any suggestion?
Probably a problem between PHP and lighttpd?
Thanks
Michele
