Hi Bruce,
Thank you for your thoughts.
The field does contain the first two hops (of four) of the routing path. With this it is quite easy to get over 32bytes. We do not use the Chairdomain field for the response by choice. There are no changes to the code. I cannot find any reference to the field within the Databases code. I thought that must be hardcoded to Notes or Domino.
Currently the sender has an non-adjacent domain doc with target: "*" - Next Domain: %NextDomain% and the %NextDomain% "should" have another adjacent and so forth. But for testing purposes I asked the admin of the source domain to create an non-adjacent domain for "My" Domain like this: Target: %MyDomain% - Next Domain: %NextDomain% this does not change anything - it still creates a defective ChairDomain field.
Today I asked the admin to send a test invitation to me appending the complete routing path to my address: Manuel Nientit/MyOrg@MyDomain@MiddleDomain@MiddleDomain@NextDomain and it worked (of course) without chairdomain field.
So the "ChairDomain" field is created when the path is not the to field. But still: the path has been found.
FromDomain does not exist...?? I am lost.
Thanks a lot,
Manuel
