You can do an easy test to see where is the delay. Synchronice your board with a NTP server, write a simple script that sends an email.
Then program a scheduled task to run the script at a known time. When the message arrives, see the message headers. The SMTP servers should be NTP time configured, so in the headers you will have a very aproximated information about the times the message spend to arrive. So finally you have the time you send, the time your server gets the mail, the transport times if any and the time you received the mail.
