I'm on Debian I'm trying to send an email to firstname.lastname@example.org but it's not working although I changed the
update-exim4.conf.conf to "internet".
It doesn't give me any output but I can't find anything in the email@example.com
The error log shows this:
The IP you're using to send mail is not authorized to\n550-5.7.1 send email directly to our servers. Please use the SMTP relay at your\n550-5.7.1 service provider
