Question
When sending messages from a mail-in database in Lotus Domino®, the From and/or Reply To Internet address is not always what you expect.
Answer
Domino populates the Reply To address in an outgoing message depending on the presence of several fields (From, iNetFrom, Principal, $iNetPrincipal)
in the message. Each field corresponds to specific information available to Notes:
From--> name on the Lotus Notes® ID being used.
iNetFrom--> address specified in the Internet Address field in the Location Document being used.
Principal--> name populated in the Mail File Owner field of the database being used.
When the From field is equal to the Principal field:
Domino will use iNetFrom. If no iNetFrom field is present, it will use the Global Domain Document, Configuration Document,
and Person Document settings to create the appropriate address.
