Most email clients, such as Eudora, Outlook Express and
many, many others are designed to adhere to accepted
standards whereby the client, not the server, places a
"message-id" on all outgoing mail.
This can be insecure for our users. If you wish to remain
as anonymous as possible, you should change your dominant
account to something invalid. We have chosen to use
"nowhere.org" as an example of an invalid account. You may
use whatever you wish, just remember that in order to
protect your anonymity, whatever you choose shouldn't have
anything to do with you or your online presence in order to
To further explain, it's necessary for you to send an
outgoing test message, from your existing "dominant"
account. If you don't have Eudora setup already, skip this
portion and go to "New Setup," below. For those that are
currently using Eudora as their mail client, try this:
Compose a new email, use any "personality" you wish to
send the message. Send it to one of your other accounts or
to the "dominant" account. It really doesn't matter who you
are sending "as" -- just make sure you send it to yourself
so you may check the headers.
Send the message, then retrieve your mail. When the
message arrives in your inbox, check the message headers.
The easiest way of doing this would be to "double-click" the
new message, then click the "blah blah" icon above the
message. The entire message header should appear. If you
look for "message-id" you will note the domain directly
reflects the domain of your "dominant" account.
If you want to increase your anonymity with Eudora, it is
advisable to change your "dominant" settings to reflect a
non-working email address. Eudora uses the "dominant"
account when setting up the outgoing message-id. The
Message-ID is mandatory and cannot be "left-out". However,
it can be set to reflect a non-working, invalid account.
If you want to modify an existing Eudora installation to
reflect a more anonymous email setup, follow these
In Eudora, click on the "Personalities" tab. Right click
on the <Dominant> personality and select
Change your settings for that personality as follows (you
may wish to make a note of your existing "dominant" account
settings so that you can create another personality with
that information afterwards):
- Real Name: "anonymous"
- Return Address: "firstname.lastname@example.org" Login Name:
- SMTP Server: "none.nowhere.org"
- Uncheck "Authentication Allowed"
Incoming Mail Tab:
- Incoming Email Server: "none.nowhere.org"
Go to the "Personalities" tab again.
Right-click on the new "dominant" account and click
Uncheck "check mail" -- we don't want to try and check
this mail, as it is false and won't work.
The following is for a new setup, not for an existing
Eudora setup. If you are currently using Eudora for your
email and you are adding a Cotse account, or you would like
to secure your existing setup, jump to "Existing
- Click on Tools --> Options
- Highlight the "Getting Started" Icon in the
- Enter the following information on the right:
- - Real Name: "Anonymous"
- - Return Address: " email@example.com"
- - Mail Server
- - Login Name: " none"
- - SMTP Server (Outgoing): " none.nowhere.org"
- - Leave "Allow authentication" unchecked.
- - Click OK.
- Click on Tools --> Personalities. The
Personalities tab will appear to the left of your inbox.
Right-click on "Dominant" and click "Properties"
- In the Generic Properties tab, make sure that "check
mail" and "authentication allowed" are both
- Click OK.
Go to "personalities". Follow the directions
for setting up a Cotse standard or SSL email account.
After making the recommended changes to the "dominant"
account, when you send mail with any email address, the
"message-id" will not reflect a valid domain or account
name. Note, however, that the numbers to the left of the
message ID are still valid dates. To our knowledge, there's
no way to modify this.
If you modified an existing account, you will need to go
back into "personalities" and setup a new personality with
the account settings of your previous "dominant" account.
The "dominant" account has been virtually disabled, keeping
you from publishing unwanted information in your email
If you use "leave messages on server", setting up this
new "dominant" account will require your client to
re-download all messages left on the server.
Eudora adds a couple other headers to your outgoing email
that you may not like, such as the "x-sender" and "x-mailer"
header. There's a well written and easy to follow document
and utility to change this.
We recommend that when you're done making the
modifications to your message-id that are described here
that you then go explore the edit-x
