Hi,

with latest amavisd-new (amavisd-new-2.3.3) seems that if the ldap
connection to the server drops (ie after being idle for sometime)
amavisd is not able to reconnect, or to explain it better, it
reconnects for for some reasons the query fails.
The only way to solve that is to restart amavisd.

here's my ldap connection params into amavisd.conf :
$enable_ldap = 1;
$default_ldap = {
  hostname => 'ldap.mydomain.net',
  tls => 0,
  base => 'o=hosting,dc=mydomain,dc=net',
  bind_dn => 'cn=phamm,o=hosting,dc=mydomaint,dc=net',
  bind_password => 'blah',
  query_filter => '(&(objectClass=amavisAccount)(mail=%m))'

};

and here's the logs from amavisd:

now I'll try to check into the code why this fails... but I'm not a
perl expert :)
