I am using your Contact Form plugin on my website. I've noticed that I only receive emails from certain email addresses and DON'T receive them from other email address.
I can send from my school's email address, and my mom can also send me an email from her school email address. For some reason, I can't receive emails from Yahoo! addresses or Gmail addresses. I haven't tried Hotmail or other addresses.
Is there a reason why this is happening?
I need to launch my website as soon as possible. Thank you & God bless!
