I have encountered a problem with sending messages containing coloured text from a Notes client running on Windows 10.
We have two Domino servers (lets call them A&B) both running 9.0.1FP3.
DominoA (internal network) sends SMTP messaging to a secure host. DominoB (DMZ) routes SMTP through DominoA
Messages which contain coloured text are having the spaces removed when sent externally, any coloured text appears as one long word. Notes client 9.0 and 9.0.1 fp6 display the same issue.
Connecting to DominoB or DominoA with a Notes client will replicate the issue. Connecting with a web client to DominoB will not replicate the issue and coloured text is formatted correctly when it reaches it's recipient.
I have tried the changing/confirming the preferences in the Notes client (Internet mail and location) but to no avail. I even tried Windows compatibility mode running as Windows 7, same results.
The fact that webmail doesn't produce the issue despite using the same Domino network leads my nose to the client.
