You can set many mail clients so that they add @psych.upenn.edu to any address without a host name. If the recipient does not have an @psych address, the mail will go to @mail.sas.upenn.edu, so this will work even when you send mail to others with accounts on mail.sas.
With Mozilla or Netscape, just set your own email address in "Mail and news account settings." Then the mailer will automatically add your own host name to any message without one.
Instructions are also available for Eudora for Windows and Eudora for Mac
With Mutt, add the following two lines to your .muttrc:
set hostname="psych" set use_domain=yes
Users of mail.sas can send mail to large groups by using system aliases or mailing lists. To post to the department mailing list, upenn.psych.general, see the instructions here. The newsgroup can also be read by anyone at Penn, e.g., undergraduates with accounts on other computers. Most psychology majors probably read it too.
System mail aliases are intended for messages that are NOT public but are, rather, intended for a particular group. To use an alias, simply send mail to it as if it were an email address on mail.sas, with the @psych at the end (or @psych.upenn.edu if you are not using a Unix mailer on the server). Again, please do not use these aliases for things that you could just as easily post to upenn.psych.general, such as messages about lost books, lost dogs, looking for subjects, participants, observers, or research assistants, houses for rent, etc.
Here are the most useful aliases we have now. (A complete list is in the directory /pkg/lib/aliases/psych/ on mail.sas). Here, the alias names are in this font. Make sure to end each alias with @psych.upenn.edu or, if you are using a mailer on a Penn server, @psych.
Here is one way to do this in elm:
enter elm and type "a" for alias
type "n" for "new alias"
type the name you want to use, e.g., "academic" after the "name" prompt
fill in the other fields as you wish, or leave them blank
in the "address" field, type (for example)
faculty, edm, emeriti, grad, postdoc, resfac, tom, dick, harry
For larger aliases, you can set up a personal alias as follows: Put the email addresses, one per line, in a file of your choice in your home directory or one of its subdirectories. The file needs to be readable by "other", and the directory where it is located needs to have the r and x permissions for "other". Then write "manager" with the name of the file.
