I am creating a contest form for various email addresses to use as a contest. this is the error message I get after the "Thank You" page comes up: Warning: mail(): Failed to connect to mailserver at "popmail.ensembletravel.ca" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in W:\Webs\ensembletravel.ca\eads\selectvacations\en\mailer.php on line 88 Should I add this code in the mailer.php? ini_set("SMTP","localhost"); ini_set("smtp_port","25"); if so where do i put it and is that all i need to add? Please help Thanks
