Do you have multiple email accounts?

And, what did the server administrator or ISP say when you contacted them?

The unidentified e-mail provider's SMTP server might've been too busy, or
down for maintenance, or down, or a node in the route between you and the
mail server is slow or unresponsive.

Could be due to the delay caused by the superfluous scanning of e-mails by
your anti-virus program. Disable e-mail scanning in your AV program.
