Using the Poprelay authentication service
Poprelay is a roaming authentication service that enables
domain users to log onto their domain mail server and send messages from
outside the network. Users must check the email messages in their account
(pop) before they can send messages (relay) from their domain account,
i.e. pop before relay.
Users must first unlock the mail server by checking mails from their account
before sending messages, failing which any attempt to send messages will
result in a 'Relaying Denied' error.
Poprelay does not require additional configuration of the mail client.
Users can directly log into their mail server from anywhere
in the world and relay messages using their domain mail account for two
consecutive days (3000 minutes). On expiration of this authentication
period users will have to again unlock their mail server in order to send
How Poprelay authentication works
When a user logs
onto the mail server from outside the network, the IP address of the computer,
from which the user initiates a connection to his mail server, is recorded
in the mail log file.
This IP address is
verified with the list of permissible relay addresses (addresses that
are authenticated to send messages via the domainís mail server). If the
IP Address is permitted to relay, then the user can send messages from
wherever he is for two consecutive days.
