How MailHurdle Protects You from Spam E-Mail
MailHurdle basically works this way:
For more information about MailHurdle, view frequently asked questions at:
- When the W & M E-Mail Server receives E-Mail addressed to you it checks its sender address against a list of addresses who have already sent you E-mail; if it sees the sender on the list, you get the message.
- Otherwise if the E-Mail server sends a message to the sending equipment, telling it that W & M’s server is busy, resend later. If the sender is a typical E-Mail server it resends and this message gets to you; then the address of the sender gets put on the list; any E-Mail with that address reaches you thereafter.
- If the sender is just squirting out spam mail to a slew of addresses, the sender does not resend; thus the spam will not reach you.
- There are occasions when the sending server is not sophisticated enough to resend in responds to the testing “try again” message from MailHurdle; then the legitimate message is barred from reaching you. Even then the sender will receive a message that their message did not go through; in most cases the sender typically resends (but not the Spam sender). The resent mail goes through; and thereafter because it goes on the acceptable list.
