sendmail problem

becard

Hello,

php version 8.1
apache 2.4
aapanel 6.8.27

I test the simple mail function because I work on a laravel project and the emails do not work on sendmail nor on smtp so I did some tests to find out why nothing works, already with the simple classic sendmail function it should work, I don't understand the problem.

I try send simple email : mail($email_to, $email_subject, $email_body)
Return true but it never happened

same with ssh : echo "Subject: sendmail test" | /usr/sbin/sendmail -v info@xxxx.com response: Mail Delivery Status Report will be mailed to <root>.
xxxx.com is changed for this post
i need change other params ?
thank you

Hello, it is recommended to check whether the sender is set, and check whether the server's port 25 is banned by the server provider
