How do you alter who the password reset emails come from?
You can change it on the FBA Site Configuration page.
I changed the reply to
donotreply@domain.com but somehow when someone replies it still comes to me. Any ideas?
Setting it on the FBA Site Configuration page should set it on the email. Have you checked the actual sent emails to see if they are from
donotreply@domain.com, or your email address? Potentially there's a wildcard rule that all unresolved email addresses go to you?
