Sending email

There are basically four ways you are likely to address an e-mail: to someone off-campus, to an on-campus netid, to an on-campus alias and directly to someone with an account on the Geology server.  
Off-campus addresses: These must be fully qualified, that is, have both the username and the location extension. For example, to send mail to Jan Smith who has a userid of jsmith and whose e-mail account is provided by AOL, you would need to address the e-mail as "jsmith@aol.com".

jsmith@aol.com

On-campus netids also need to be fully qualified when used as e-mail addresses. The format is <netid>@email.byu.edu.

js43@email.byu.edu

On-campus aliases are similarly constructed. If Jan's alias is Jan_Smith (a common format for BYU aliases), you would enter Jan_Smith@byu.edu. Note that the location extension does not have the "email." in it.

Jan_Smith@byu.edu

By default, the Geology mail server assumes that any address missing the "@whatever.net" goes to someone on the Geology server. If Jan's Geology account id is js43 and you are sending mail to her from Pegasus mail, that's all you need to enter in the address field. The server will automatically add the "@geology.byu.edu" to the id and handle it accordingly.

js43

To summarize:

Off-campus addresses: <userid on remote computer>@<location extension>
On-campus netids: <netid>@email.byu.edu
On-campus aliases <alias>@byu.edu
Geology user: <geology id>[@geology.byu.edu] (The location extension can be left off. It is provided automatically when no location extension is specified.)
