PHP Contact form

[Nishada]

Now I'm editing a PHP contact form to get visitor's comments to my e-mail. 03 fields are there as Name, E-mail and message. If visitor fill the e-mail field as yahoo.com or hotmail and any other famous mail server addresses, I can't receive that comment. Please give me instructions to correct this.

If you receive mails from other addresses but not from yahoo, hotmail ... check your spam folder. maybe your hosting server has this names in its black list ....
