emails arrived long after senders sent them

emails arrived long after senders sent them

Hi,
I've noticed that emails have been delivered with delay. Sometimes it took a day to get a message. This morning it took about 20 mins to get emails. The below is a header from one of emails delivered with delay.

The header said it was received at 7:07 PDT but it was delivered onto my mailbox at 7:24am.
This is just one of many cases. 
Could you please check this out for me?
