send and receive emails from my website

On the Contact form, you would need a script in the background that processes the mail.  This can be a very small php send mail script.  If your host allows you to send mail through their servers, you point it to there.  If you want to go through your Google Account, you put those credentials in.

As far as Outlook goes, if it keeps asking you for the username and password, it isn't authenticating properly.  Make sure you're using the right method (POP3, etc.) that Google has in its directions.

Ok I am going to do it through this google apps account.So i have those textboxes and a button My host allows php scripting. What php script should i use with the textboxes and the button?(with the google account)

In the google app account I have created a username and a password. Then i have tried configuring outlook...with username=(the google app username) and password="the google app password"  ("prof.vijaykumarmhandre@bictr.com" and password as "bictr1234") I have passed the captcha test.

Incoming mail server=pop.gmail.com
smtp(out going mail server)smtp.gmail.com

port numbers:

pop3:995
smtp:587

ssl at both the check boxes

sorry for any ignorance and thank you for replying

Real quick, if that's your actual login information, immediately request moderator attention and remove that.  You don't want it pasted in the open here.

ps: I had another account in my outlook which was why it was asking for username and password
