How to control 'mailed-by' and 'signed-by' in email delivery

[supratim320]

Hi All,

In adobe campaign, we can control the reply-to address and text. However, I could not find any provision to control - 'mailed-by' and 'signed-by'.

In gmail, I can see that both 'mailed-by' and 'signed-by' are by default the environment domain.

My question is: is it possible to control these entities?

Thanks & regards
