550-unrouteable mail domain "localhost"

Hello everybody;

I installed a software called cuteflow. All parts of the program are doing fine except when trying to send a message to the user, I get this error message.

There is also one part of the program called 'notification' but it is doing fine also, so I don't think the smtp portion is problematic cause the notification emails are well sent and received.

Anybody has a brilliant idea how to solve this? I'm no php expert.

Without seeing the code it's impossible to say what the problem is, but from the error it would that the account that the script is sending from doesn't have permission to send mail.. If the script is already sending emails then is it could be something else though.

I would trace the error back to whatever line is causing the problem, and see if anything can be fixed with that specific code.

 

jestep: thank you. up until now i'm still confused whats causing the problem. the software is open source so there is no full support.

thank you. but i have really a hard time understanding those.

 

Here's a guess: to run cuteflow you also loaded php on your system and there's a file called php.ini that needs to be configured to point at your smtp server. Just find the file and search for the string localhost and replace that with your smtp server's host name.

 

To be precise, open your php.ini and search for [mail function] you should update below line to your setting.

SMTP = <smtp server>
sendmail_from= <whatever>
