It's happened to me that messages that reached my ISP only reached
me hours and even a day and a half later. They were having a
collapsing smtp-server and because it went down uncontrolled the other
servers got overloaded and went down one after another.
As soon as they were up to the problem, the mail flow was ok as far as
the new messages were concerned, but the older messages were inserted
slowly in order to prevent the network from overloading again.

Servers are only computers, sometimes they mess up in a big way and
those messages are mostly restored, since the sysops find out.
Sometimes they're forgetting just one message and nobody finds out.

Sometimes the communication between two servers goes amiss, causing
the receiving server to time out, whereas the sending machine thinks
it has delivered properly. Of course that's sloppy programming,
because the protocols are written such that it would be very more
likely two receive two copies due to faulty communication than none,
but alas programmers are only human.
