How Mail flow in Lotus Notes and Domino

NRPC Mail Flow

Notes client,which is used to create the message and transfer the message to the Domino Server.

The message is transferred via NRPC to the Domino Server .

The message is written to the Mail Box database on the server.

Note: This database(mailbox) ACL -Default- access is set to Depositor so

users can “deposit” mail but cannot read any of the messages waiting for delivery.

By default the message is also saved in the sender’s Mail database on the user’s Home/Mail server for later reference.

The Router server task uses the Domino Directory to determine where to transfer the message. If the destination Domino Domain is:-

>the same as the server’s, the Router looks up the recipient’s Person document in the Domino Directory to find the recipient’s Home/Mail server name.

>in another Domino Domain, the Router looks up the Connection document to a Domino Server in that other Domain.

If the message is destined for a user on the same Home/Mail Server as the sender, the Router delivers it immediately. Otherwise, the

Router copies the message out of the local Mail Box and writes it to the remote Mail Box database on the target Domino Server using the NRPC protocol.

If successful, the Router then deletes the message from the local Mail Box database.

The Router server task uses the Domino Directory to determine where to transfer or deliver the message. If the recipient Mail database is on:

> the same server, the Router looks up the recipient’s Person document to find the Mail database file name

> another server in the same Domino Named Network, the Router immediately transfers the message to that server via NRPC

> another server in a different Domino Named Network, the Router looks up the Connection document to a Domino Server in that

other Domino Named Network and transfers the message via NRPC.

Whether for message transfer or delivery, the Router stamps its name and the current date/time that it handled the message.

The Router checks any user mail rules that may delete or modify the message. If not, the Router copies the message out of its local Mail Box and writes it to the user’s Mail database using the NRPC protocol.

The Router deletes the message from its local Mail Box database.Notes is used to read the message from the server copy of the Mail database. This is just like reading any other Domino database.The message is retained in the user’s Mail database on theserver until explicitly deleted by the user (or archived to another database via an agent running in the Mail database).
