This question is related to wordpress about the contact form syntax. Any help?

can anyone solve this error “Invalid mailbox syntax is used”?

I have followed a tutorial on youtube where it was given:- admin@domainname in From. but it’s not working. I am using AMmps server.

You need to use the hostname of your web server.
