This is for a school project
I’ve got a couple of virtual machines set up, a server and a client. The client can log into the server as one of two accounts, and send an email to the other account
The next thing I need to try and do: when an account sends an email, a small line of text is automatically added to the email’s header. Then the second account receives that email, inspects the header and sees that text.
The text itself would just be “yay it worked” or something along those lines.
Does mailcow have an inbuilt feature that can be used to do this? If not, any recommendations for add-ons that could help?
