Restrict Postfix From domains
Protecting postfix from bruteforce attacksCNAME: Mail address gets rewrittenPostfix: force local users (PHP) to use the SMTPD for outside recipientsPostfix Relay Multiple Domains with Multiple OriginsPostfix virtual aliases & domains?Postfix: Users impersonating other users at same domainHow do I setup Postfix to fulfill these requirements?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;

I have a webhosting server based on ISPConfig (Debian 9.9 LAMP) and I'm new to Postfix. When users send an email from PHP, the default address is webmaster@thedomain.com. This address can be overriden, but I want to disallow them to override the domain part.
The correct way seems to be to configure header_checks
to check the uid in headers and correlate it with user's domains in database.
Another thing I found is Milter, which also looks like a good tool to achieve this, but it seems to be a bit overkill.
Has anyone configured something like this? What do you think is the correct way and why?
