Hi everyone 
Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()Can someone help me please 
Your script failed to connect to the mailserver on the same server. You need to verify your SMTP and smpt_port settings in php.ini (or you can set them using ini_set())
Iām presuming you have a mail server running on the same machine as you are executing PHP? Make sure you use the correct settings for connecting with it. If not, install one.
