Due to our anti-spam devices it's not unusual to experience delays when
receiving emails from external sources.

The university implements a technique called "greylisting". In a nutshell,
greylisting rejects any email we received if it is coming from an unknown
sender (eg: an email address we haven't seen before).

Most spammers don't send their messages twice, which significantly reduces the amount of junk we have to deal with.

The delay in how long it takes for emails come through depends on who is
sending the email, and how often the email service is set to resend the
message. It's unfortunate, but some email services just don't work well
with the service.

If you suspect there may be a problem receiving emails from external parties, please contact the Support Desk.

It's also possible that the message being sent to the U of M is being caught by the spam filter. Please read this FAQ on our junkmail filter.
