emailaddress.Check()

This package contains two functions to check email addresses.

An email address name must respect rules presented in https://en.wikipedia.org/wiki/Email_address.

The emailaddress.Check function ensures that the email address respect those rules. If not, it returns an error explaining the detected problem. This function accepts emails without a domain like "root" which is valid on unix systems.

The emailaddress.CheckWithDNS() calls Check and also checks that the domain after the last @ is an existing domain accepting emails. With this call the email "root" is invalid since it has no domain accepting emails.

Prerequisites

The package has no prerequisites. It depends on github.com/chmike/domain@v1.0.0 to verify domain names.

Installation

To install or update this package use the instruction:

go get -u "github.com/chmike/emailaddress"

Usage examples

The Check function can be used to check the validity of host or domain names.

import "github.com/chmike/emailaddress"

. . . 

emailAddress := "foo@example.com"
if err := emailaddress.Check(emailAddress); if err != nil {
    log.Fatalf("invalid email address '%s': %v", emailAddress, err)
}
