Have a Thunderbird Imap client, connecting to a converted IMAP mail file on Domino server. User connecting is part of the xyz.com domain. On the Thunderbird client inbound server is confiured as planet.xyz.com and outbound server is also configured as the same server planet.xyz.com. When sending email out it fails stating relay problem. Although there are other servers in the domain responsible for routing mail, for this particular user I want to avoid mail relay checks, send email out smtp from the planet.xyz.com server using SMTP from this server only for this user. Is there an outbound control setting that would allow that. I have a fully qualified LN address and also the Internet address taht I could use.
