PHP : send mail in localhost

It is configured to use localhost:25 for the mail server.

The error message says that it can't connect to localhost:25.

Therefore you have two options:

1. Install / Properly configure an SMTP server on localhost port 25
2. Change the configuration to point to some other SMTP server that you can connect to
