postfix 3.5.X: Issue with reconstruction of long header lines (suspect: smtp)

Hi everyone, I think I stumbled upon a problem with postfix 3.5.X and very long header lines. To reproduce, I build a very simple setup with two VMs: - "A" running postfix 3.3.0 (xubuntu 18.04 package) - "B" running postfix 3.5.6 (xubuntu 20.10 package) Both are relayhosts for each other and a
