In this video, Chaim Krause sends email to an external email account using Postfix. This is done to test postfix without adding the variables of an email client.
- [Instructor] So at this point,…we're able to send email between local users.…What we want to be able to do is send mail externally,…and receive mail from an external location.…So we're going to need to take our post fixer…and change some of the configurations to work externally.…The file we need to change…is in /etc/postfix/main,…and this is a long file, with a lot of stuff in it.…
There's sort of two ways you can go about this.…One is, you can try and find each one of these variables…in the file, and then make the change there,…and I suggest that's what you do most of the time.…If you are just testing, you can go to the end of the file,…and enter in all this information,…because the way it works, if you define your variable…a second time or a third time,…whatever you define it as last is what it's going to use.…
So, once again, for testing, you can just…go to the end of the file and add this,…but when it comes to actual production,…you're going to want to go through the file…so you've got the proper documentation.…
