Keep in mind that SMTP mail delivery is a store-and-forward process. 
Look at the headers of a message and see how many Received: headers 
there are. Each of them represents a hop (server) through which the 
message passed and on which it was stored and queued for outgoing 
delivery to the next server in the chain. If anything interferes with 
delivery from one particular host to the next, it keeps the messages in 
its queue until it can successfully deliver it or until some timeout 
(often measured in days) expires and the server bounces the message 
back to its originator.
