7.10 Managing Mail
When managing user accounts, you might have to manage a user’s mail account.
For example, you may want to perform the following tasks:
• Change a user’s mail profile; for example, change a user name or specify a
default print queue for the account
• Set a forwarding address for a user who has moved to another location
• Disable a user’s account from receiving mail
• Customize a user’s mail environment by setting flags in a user’s UAF record
The following sections explain how to perform all of these tasks.
7.10.1 Modifying a User Record
All users can modify and display information about their own records using
various SET and SHOW commands available within Mail. These commands
access SYS$SYSTEM:VMSMAIL_PROFILE.DATA, which is a single-key indexed
sequential file containing information for each user.
With SYSNAM, you can change the mail forwarding address for a user (including
one without an account) on the system with the Mail utility command SET
FORWARD/USER=user.
7.10.2 Removing a User Record
Typically, once you have deleted a user’s record in the UAF, you will also want to
remove that user’s information from the user profile database. You can remove a
record from the user profile database with the REMOVE command.
7.10.3 AUTHORIZE Flags and Mail
Certain flags set in a user’s UAF record can affect the user’s Mail environment.
You can set the appropriate flags in a user account by specifying the following
flags with the /FLAGS qualifiers using AUTHORIZE:
Flag Meaning
[NO]DISNEWMAIL Enables or disables the display of the new mail count when the
user logs in to the system.
[NO]DISMAIL Allows or restricts the receipt of new mail.
7.11 Managing System Resources
This section contains detailed descriptions of the resource control attributes you
can assign to a user process when creating a record in the UAF.
7.11.1 Understanding Pages and Pagelets
VAX and Alpha systems allocate and deallocate memory for processes in units
called pages. A page on a VAX system is 512 bytes. On Alpha systems, the
page size will be one of four values: 8KB (8192 bytes), 16KB, 32KB, or 64KB. A
particular Alpha system will implement only one of the four page sizes and the
initial set of machines use an 8KB page.
