For 18 sec (from 15:25:37 till 15:25:51) i found twenty "C: a001 LOGIN" operations. Is this normal?
Maybe something wrong with my settings? Here are some of them:
...
$rcmail_config['session_lifetime'] = 60; (minutes?)
$rcmail_config['min_keep_alive'] = 20; (sec)
$rcmail_config['email_dns_check'] = false;
$rcmail_config['keep_alive'] = 30; (sec)
...
