=== Introduction ===

Several of IPP people have been having problems with delays in email.  I'm running an experiment as follows:


 * cron job every hour at :00 from exim4 and my desktop (so the email is user@(computer).ifa.hawaii.edu)
   * sends an email (with date and time) to @gmail
   * sends an email (with date and time) to @ifa
 * record the time my gmail account receives the email
 * record the time my ifa account receives the email
 
=== Plots ===

Here are daily plots of email delays
