PMDF User's Guide
OpenVMS Edition

If you want, other users can use aliases which you establish. This is particularly useful when you want to set up a mailing list which you want other people to post messages to. (See Section 9.3.3 for details on setting up mailing lists.) You allow other people to use specific aliases of yours by declaring those aliases to be public. This is done with the "attributes" parameter of the "set" command described in Section 9.3.7.12.

For example, let us assume that the user sue@example.com has already created an alias named PIZZA-ORDER. Then, to declare PIZZA-ORDER to be a public alias, Sue would use the command

db> set pizza-order public

Other users can then use this alias by sending mail to sue+pizza-order@example.com.
