New user registration: Send mail to server mailboxes only.
I have recently installed PHPlist. I did a test of user registration. PHP list sends the registration confirmation email only to the mailboxes that are managed by my server.
It does not send emails to other mailboxes.
Then I also tried to set up an external SMTP and I entered this code (with the data of my mailbox).
$phpmailer_smtpuser = ‘email@example.com’;
$phpmailer_smtppassword = ‘user_password’;
I also entered other ports (25, 465 and 587) but I get this error in the event log:
The following From address failed: firstname.lastname@example.org : MAIL FROM command failed,6rsml22jjOKZy6rsmlAIgJ invalid domain ,550,5.1.0SMTP server error: MAIL FROM command failed Detail: 6rsml22jjOKZy6rsmlAIgJ invalid domain SMTP code: 550 Additional SMTP info: 5.1.0SMTP server error: MAIL FROM command failed Detail: 6rsml22jjOKZy6rsmlAIgJ invalid domain SMTP code: 550 Additional SMTP info: 5.1.0
Do you have any ideas? Thank you
