Management Instruction AS-870-2010-1, Electronic Messaging

Management Instruction (MI) AS-870-2010-1, Elec­tronic Messaging, is now available on PolicyNet and is effective immediately. All previous MIs dealing with elec­tronic messaging are obsolete.

The MI has been revised to update procedures and clar­ify policy on e-mail usage, security, and storage capacity allocated to Outlook users. Some specific changes are:

n The manager, Information Technology Engineering and Architecture approves any application change that impacts e-mail in terms of number of messages and associated schedule.

n Any e-mail considered to be a “chain e-mail” or an e-mail of religious or political nature will be considered misuse and can lead to suspension of e-mail.

n Outlook users can check their mailbox size by open­ing Outlook, then clicking Tools, then Mailbox Cleanup, and then View Mailbox Size. Alternatively, use “Alt + T” to open the tools menu, then “X” to open Mailbox Cleanup, then “M” to view mailbox size.

n Outlook signature blocks are restricted to essential contact information: name, title, organization, phone number(s), and e-mail address in a basic font style. Additional elements including graphic images; ani­mations; a URL; inspirational, religious, or political messages; or a stylized background are prohibited.

MI AS 870-201-1 is available on the Postal Service™ PolicyNet website:
