I am trying to send my gmail id to Ubuntu via php script but it is unable to send my code

  & lt; Html & gt; & Lt; Head & gt; & Lt; Title & gt; Send mail & lt; / Title & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt ;? Php $ name = $ email = $ query = ""; If ($ _ server ["REQUEST_METHOD"] == "POST") {$ name = test_input ($ _ POST ["name"]); $ Email = test_input ($ _ POST ["email"]); $ Query = test_input ($ _ POST ["query"]); If (mail ("abc@gmail.com", "subject", $ query, "sender: $ email \ n")) {resonant "send email"; } Else {resonance "do not send"; }} Function test_input ($ data) {$ data = trim ($ data); $ Data = stripsash ($ data); $ Data = htmlspecialchars ($ data); $ Return data; }? & Gt; & Lt; Form method = "post" action = "& lt ;? php echo ($ _SERVER [" PHP_SELF "]) ;; & gt; & Gt; Name: & lt; Input type = "text" name = "name" required & gt; Email ID: & lt; Input type = "email" name = "email" required & gt; Query: & lt; Textarea name = "query" line = "5" cols = "40" required & gt; & Lt; / Textarea & gt; & Lt; Input type = "submit" value = "submit" & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt;  

I have configured my php.ini

  [mail function]; For Win32 only; Http://php.net/smtp SMTP = Localhost; Http://php.net/smtp-port smtp_port = 25; For Win32 only; Http://php.net/sendmail-from; Sendmail_from =; For Unix only you can supply logic as well (default: "sendmail -t -i"); Http://php.net/sendmail-path sendmail_path = "/ usr / sbin / sendmail -t -i" extension = php_openssl.dll // removed semicolon  

output / var /log / Mail.log

When I submit the form, sending this email (according to my script) is showing, but I am receiving my email Gmail ID. Am I missing a configuration and installation?

Any help would be appreciated

Reputation of domains sending Gmail (and most mailing service), a combination of sending mail transfer / server status Blacklisted etc.), number of request frequency, number of recipients, and mail content to determine if mail is spam or not.

If it determines that it is not, it transmits it to the inbox, in the case of moderate intensity it routes to the spam folder. If the rating is actually low, then it blocks the mail as your block.
