This update for Compuserve members is
cut and pasted from a CIS web page posted December 11,
making changes to the e-mail server configuration that
may affect the way you send e-mail. What does this Mean?
closing the relay functionality of CompuServe e-mail. To
understand e-mail relaying, it is important to first
understand the normal e-mail flow. Typically, e-mail
generated at one site recognizes the delivery address and
delivers mail directly to that address. Imagine e-mail
taking a direct route from point A to point C, bypassing
any potential middle site. In the case of e-mail
relaying, however, e-mail generated at one site gets
passed to an intermediate site before reaching its final
destination. The intermediate site then forwards, or
relays, the e-mail to the final address. The path, then,
is: mail generated at point A is sent to point B, and
then relayed from point B to point C. When this happens,
it can appear to the end site that the e-mail was sent
from the relay site (B) instead of the originating site.
Consequently, when CompuServe is used as a relay site,
the receiver of the e-mail legitimately believes that the
mail was generated from CompuServe.
Why is CompuServe
Closing the E-Mail Relay Functionality?
E-mail relaying is
one method used to deliver Unsolicited Bulk E-Mail,
commonly referred to as spam. Users who engage in this
unethical practice forge mail, which makes the mail
appear to have originated from an address such as
CompuServe. Deactivating e-mail relaying will permit only
those users with CompuServe e-mail accounts to send mail
from CompuServe, thus preventing CompuServe computer
resources from being used to process spam.
The delivery of
spam negatively impacts CompuServe in three ways: it
causes other sites to refuse mail from CompuServe; it
increases the load on the mail machines; and it damages
CompuServe's reputation as a cooperative member of the
What You Need to
These changes are
part of an effort to improve e-mail traffic and security,
to improve connectivity, and to reduce junk e-mail.
15, 1999, if you connect to CompuServe using a LAN or an
ISP other than CompuServe, you may need to change your
third-party e-mail software settings AND the e-mail
settings in your Web browser. Once these settings are
changed, your ability to send e-mail will be unaffected
by the changes we are making to our server configuration.
Who is NOT affected
by this change:
-- Members sending
e-mail via CompuServe software, such as CompuServe 2000,
CompuServe version 4.x, 3.x, 2.x, etc.
-- Members who
connect directly to CompuServe using a dial-up modem
connection and a CompuServe access number.
*If this describes
how you connect and use CompuServe e-mail then you do not
need to make any changes to your e-mail seetings.
*Who may be
affected by this change:
-- Members using
third-party e-mail software (e.g., Outlook, Netscape
Communicator, or other third-party e-mail clients) to
SEND mail AND
-- Who are
connecting to CompuServe through another ISP (Internet
Service Provider) or LAN (Local Area Network).
*If neither of these instances describe your e-mail
connection, then you are not required to make any changes
to your mail settings.
CompuServe members do?
*Go into your third
party e-mail client and view the mail settings. (Contact
your LAN administrator if you need assistance accessing

obtain from them their SMTP server address.
-- Change the mail settings in your Web browser AND in
your third-party e-mail client to reference your ISP or
LAN's SMTP server.
*What happens if
these changes are not made?
If these changes are not made, then you will not be able
to send e-mail. Depending on your e-mail software, you
may receive an error message indicating you cannot send
mail or that there are problems with connecting to the

Compuserve POP3 Mail is
available for Windows 95, Windows 98, Macintosh, and
Windows NT 4.0 or greater users.
What is POP3?
POP3 (Post Office Protocol version 3) is an Internet Mail
standard. This is different from the CompuServe Mail you
are currently using with your CompuServe software. POP3
is the mail system that allows you to use web browser
mail software, or other e-mail software packages such as

What is CompuServe Virtual Key?
CompuServe Virtual Key keeps your information private and
prevents others from using your account. Virtual Key is
also known as RPA (Remote Passphrase Authentication).
Most POP3 software does support Virtual Key. However,
e-mail software that does not support CompuServe Virtual
Key will require a mail-only password.
What is a mail-only password?
A mail-only password is a specific password used only for
your CompuServe POP3 mail account. This password will
allow you to gain access to your POP3 mailbox without the
use of CompuServe Virtual Key software. NOTE: You must
use Virtual Key to access the Mail Settings area, even if
you are using your mail-only password to retrieve your

address. For example, if your address is
firstname.lastname@example.org, your POP3 address will be
My POP3 address used to be @csi.com and everyone knows
this address, do I inform everyone of the new address?
The transition will take care of redirecting your mail to
@compuserve.com, so any mail sent to @csi.com will be
redirected to @compuserve.com. Even with redirection it
is advisable to inform everyone of your new POP3 address.
How do people send mail to my POP3 mail address?
To send to your POP3 mail address, have them address mail
to you in the following way: email@example.com.
Can I change my Personal Address after I begin using my

address. Go REGISTER.
POP3/SMTP mailboxes have the following limits:
Maximum Message Size 10 MB
Maximum Session Size 10 MB
Maximum Message Recipients (per message) 100
Maximum Mailbox Size 30 MB
Mail Storage per Message 45 Days
If I use CompuServe POP3 Mail will I still be able to use
mail with my CompuServe software?
Yes. Actually now you have two views into the same
mailbox. You will be able to access you mail through
either your POP3 software or your CompuServe software.
Note re. Compuserve:
Sorry, but at the
moment the only way to get access to the Compuserve news
server is to log on to Compuserve via one of the many
Compuserve access telephone numbers. Logging on from a
different ISP is not supported at this time.
