Hallo everybody, Thank you Edward for answer! Indeed, there is a big chance that the filter i am talking about in the Original message will
remove a valid email addresses. However, there has to be at least two of the following characters!#$%&'*+-/=?^_`{|}~@.[] in this email address.Does someone agree with this statement?

FILTER_SANITIZE_EMAIL Remove all characters except letters, digits
