I'll fix it. However there is something that I do not fully understand and I thought it was not strictly required when forwarding patches like I just did. How do you handle the very common case in which the patch author is the corporate email address, but the email sender is a private one? Normally you have: - sender me@xxxxxxxxxxxxxxxxxxxx - first line of the email From: me@xxxxxxxxxxxxxxxxxxx - SoB: me@xxxxxxxxxxxxxxxxxxx with that the email sender does not match the last sob, but this is very common, see for example https://lore.kernel.org/all/20220705085825.21255-1-max.oss.09@xxxxxxxxx/ Should we have an additional - sob me@xxxxxxxxxxxxxxxxxxxx Therefore having 2 sob by the same individual, but with 2 different email addresses?
