comment After ntpdate update for ubuntu server I always receive the old php file in nginx
@TeroKilkanen Yes, NTP poles its servers and adjusts the local clock to keep it correct. In most cases, this can be done by polling every 1024 seconds. My hosts are kept withing a few milliseconds of the correct (atomic) time.

@billw /usr/bin/mail runs the local sendmail program to deliver the mail rather than connecting over the network stack. In your case, exim4 is used as a dropin replacement for sendmail. The mail will be treated as a non-smtp deliviry. Rate limiting will need to be done using a non-smtp ACL.
