Mail sent from outside UCB to someone with a UCB account goes to one of three hosts that answer all mail sent to Colorado. EDU e-mail addresses. These hosts are machines just like spot, ucsub, etc., but have other functions and different names. They are called boulder.colorado.edu, refuge.colorado.edu, and cs.colorado.edu. 2. Generally, electronic mail is almost instantaneous.
Many hosts have secondary mail hosts set up.
For example, if ucsu is not available, mail for ucsu will sit in ucsub's mail queue and will be delivered once ucsu becomes available. Most ITS-supported hosts will queue mail for three days before it is returned to the sender as undeliverable. Most ITS-supported hosts send a warning message to the sender after a message has been queued for four hours, letting them know the message is in the queue and scheduled for later delivery. This is entirely dependent upon how your mail client is configured. Now, Pine, if so configured, will store sent messages in a folder called sent-mail.
