Password Reset not sending email

[tahbikat]

Sorry for posting so many threads, but I'm having another issue with the password reset this time.

A beta tester on my site reported this to me. She tried resetting her password by entering her info into the Forgot Password fields, and it said an email was sent but she said she never got it.

I double checked with a tester account and I'm not getting the email either.

Can anyone help? :c

And yes, we've checked our junk folders.

EDIT: Okay, I know why. I checked the site email and there's emails in there saying this:
