Inbox - empty email list!!!

[adrian]

Hi everybody

I can't see emails in the preview mail list on the main page for the Inbox folder (the other seem to work)! But in the meantime I can see in brackets in the left column the number of emails that I "should" see (Inbox (3))!
Moreover, sometime I see only new mails in the list (in bold) as I'm refreshing once or twice... but still not the other ones. As if it could read mails in "Maildir/new" folder but not in "Maildir/cur" folder...
The imap server is working great and procmail moves mails in the right folders...

Could you help me please with this issue?

It seems that it is linked to fetchmail because when I try to send a mail from localhost I can see it in the list.
When I retrieve a mail using fetchmail I can see the counter increase in the left column but the list becomes empty...
Help please!
