I have a primary address book (domino domain “A”) and I also have a secondary address book (non-notes users with internet email addresses - domain “B”). In the person doc of user in secondary address book, I have set Mail System to “Other Internet Mail” and the domain to “B” and also enter their email address. If I type in a new memo To field: Joe Test/B, I get an error “No route found to domain B…”. I’m not quite sure what I need to get this to work…to send email from notes to external users in a secondary address book?
