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.

- Important: 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.

- Note: 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 email messages.

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 domain’s mail server). If the IP Address is permitted to relay, then the user can send messages from wherever he is for two consecutive days.
