email to lead auto-association not working - Please HELP

[rutavirtual]

I supposed that if I have a lead record, and then, I receive an e-mail from this lead, SugarCRM would be able to auto-associate the e-mail with the proper lead, but this auto-associations are not working.

Moreover, when I quick-create a lead from an e-mail, the lead e-mail field does not auto-populate.

I tried with POP and IMAP e-mail accounts with the same result

Is this right?
Thanks a lot

Leads do not auto-associate ... it's a manual process

Contacts do?
