First off, This Domino server I didn't set up and the person prior me I think had a few screws loose. Anyway, I'm more of an exchange guy so some of the things Domino does just doesn't make sense.
We have been having some issues with email being sent to us. The domino server will accept emails such as <lastname>@mydomain.com when it should be first initial and lastname. Now I did find where that was happening. I made the Change in my Router/SMTP portion in the Configuration document to Fullname. Saved and restarted the router. When that happens. Aliases that people have listed in their person document get rejected by SMTP. I can't for the life of me figure out why. I looked in the &Users view which is where I understand the lookups occur and it seems like its in there but it still doesn't accept them.
I also realized that we never had a global domain document configured in our Domino server either (what a mess). I think I have that setup correctly, however I'm not 100% for sure.
I need to get this taken care of so I can move on to my next project. I would be happy to provide any info you may need.
By the way we are running Domino 7
