How to change "mailed-by" :


I want to change the hostname to domain-names in mailed-by

I wouldn’t do that @Adhenra you may have problems with SPF records and those emails. What is the problem with that. Do you need to debrand your hosting services?

I want to do this changes because I don’t want to leak hostname with domain name.

Its now displaying signed-by: domain-name
but for mailed-by: hostname of the server
