Quarantine

A place that a mail server or mail program will put suspected spam. Generally if there is a high amount of spam in the quarantine area, real message will get lost, or be delayed.

Note that if the mail was rejected instead of quarantined, the sender would have received a bounce generated by their mail server, so would know that the mail was not delivered, so would have been able to make arrangements to get a time critical message.

Ironically, the tagging / quarantine systems are put in because of fear of rejecting a real mail message, but by not issuing an SMTP reject, they introduce human error, and are probably more likely to cause a time critical message to be lost or delayed.
