With debug enabled I got this one:

authdaemond: ldap_search_st() failed authdaemond: authldap: TEMPFAIL - no more modules will be tried ... courieresmtpd: error,relay=x.x.x.x,from=<x@x.x>,to=<x@x.x>: 400 Service

temporarily unavailable.

Why does ldap_search_st() fail randomly? What's its return code?

Hi, it seems I solved the problem rising the LDAP timeout setting the parameter "LDAP_TIMEOUT 60" in ldapaliasrc and authldaprc files.

Is it correct?

Well, it doesn't fix your problem, just masks it. For some reason your LDAP server is taking extraordinarily long time to respond. You need to take a very close look at your LDAP server, and fix whatever's broken.
