func ValidateDomainByResolvingIt ¶
ValidateDomainByResolvingIt queries DNS for the given domain name, and returns nil if the the name resolves, or an error.
func ValidateEmailByResolvingDomain ¶
ValidateEmailByResolvingDomain validates email address by looking up MX records on its domain.
This function can return various DNS errors, which may be temporary (e.g. caused by internet connection being offline) or permanent, e.g. the host doesn't exist or has no MX records.
The function returns nil if email is valid and its domain can accept email messages (however this doesn't guarantee that a user with such email address exists on the host).
