Where can I edit the standard email adress?

I've recently installed and configuered mailsend on my dedicated linux server. And when I am trying to send away a test email the email adress automatically becomes root@email.minecraftcommunity.org and I wonder where I can change the default email.

I wanna be able to change the default email anyway though, and adding that will only change the "root" on the adress
Locate and edit main.cf - should be in /etc/postfix
Add to the end of the file

smtp_generic_maps = hash:/etc/postfix/generic

...and save.


...and add on the end

root@email.minecraftcommunity.org  you@youremail.com

Sorry I am using sendmail
Don't know why you would want to use the ancient sendmail especially as you are just setting up mail on the server.
Postfix (with Dovecot if needed) is the common MTA to use on Linux these days.

I will see if I can find anything on the setting, but their config files are near impossible to read.
