Junk E-mail Dos and Don’ts





Don’t give your e-mail address to every website
that wants it, decide if it’s necessary or if it’s
something that you really want to receive
Do Look for “opt out”
boxes
Don’t unsubscribe from something you never
subscribed to (meds4u.com)
Do unsubscribe from something you did subscribe
to (travelocity.com)
Do read Privacy Policies – look for phrases like
“will share your information with third parties who
may offer services that may interest you” (SPAM!)
Junk E-mail Dos and Don’ts

Do consider acquiring multiple e-mail
addresses



Use your work address primarily for work
Register for a free e-mail address for personal
use
Consider registering for a third e-mail address
that you use solely for registrations that you
think you may need
 Hotmail.com and Yahoo.com offer free e-mail
but are also notorious for hosting spammers
 Gmail.com (google e-mail) Gmail is virtually
spam free - an invitation is required but any
one of your Computer Support Specialists can
send you an invitation if you’re interested

E-mail comes to campus @okstate.edu
Gets filtered by Spamblocker*
Goes on to mail server
Gets sent to your computer where it gets filtered
by your local e-mail program (Netscape or
Outlook both have junk mail controls built in)
Spamblocker vs. Local Junk Filters

How do I tell them apart?


Listed in an e-mail = spamblocker
Junk Mail folder = local junk filters

Where should I add a “safe sender”?

Where should I add a “blocked sender”?

Where should I look for messages I may be missing?
safe sender = messages from this user will never be quarantined by
spamblocker, and will always be delivered to my inbox
 Depends on which system blocked it
blocked sender = messages from this user will always be quarantined
by spamblocker and will never be delivered to my inbox
 On the Spamblocker system, then the message is never
downloaded to your computer

Both! A legitimate message may have been flagged as Junk Mail
by either system, check your digest and your junk mail folder

In the unlikely event of a “false positive”
Safe Senders and Blocked Senders lists to correct
inaccurately classified mail
Blocking a Domain is more useful than blocking
individual senders (@noname.com)
If you’ve got the Google or Yahoo toolbar you
may need to turn off Popup Blocker or you may
receive error messages such as “Invalid
Credentials” or “Settings not Saved”

Lists Page – Why and How?




An e-mail you really wanted to receive got blocked? Add
them to your Safe Senders list. (add @okstate.edu here)
You continue to get junk mail from [email protected],
add them to your Blocked Senders list.
In the Lists window, click New, add the criteria you want
to declare “Safe” or “Blocked” and press Save
If you’ve got the Google or Yahoo toolbar you may
need to turn off Popup Blocker or you may receive
error messages

You can disable the digest message…
 So that it doesn’t send you e-mails stating
that “0 messages have been blocked”
 So that no digest e-mails are sent to you
You should login to the spamblocker system
and upgrade your settings to “Filter All Spam”
Be sure to hit

“Successfully Saved Settings” in the
upper right hand corner!

E-mail Client Junk Mail Filters –

Netscape Junk Mail
filters out e-mails
that it suspects
may be junk or
unsolicited and
moves it to the
Junk Mail Folder




Place a check in all four
boxes
Change setting by Junk
folder on: to “Local Folders”
(this saves space on the
server)
When I manually mark…
If you are confident that
messages you mark Junk are
safe to be deleted, select
“delete them”. If you’d like
the option of retrieving
them, have them moved to
the Junk folder.
Safe / Blocked Senders – Netscape 7.x



Adding someone to your
address book makes them
a “safe sender” and
messages from them will
not be sent to the “Junk”
folder*
Netscape does not have a
“Blocked Senders” list, but
instead has an option to
mark messages as Junk
using the Junk/Not Junk
buttons
Netscape will “learn” what
messages you consider to
be junk based on this*
