RFC 2822 support in System.Net.Mail.MailMessage RRS feed

  • Question

  • Does System.Net.Mail.MailMessage support complete RFC 2822 standard?

    In other terms, do SMTP emails sent using System.Net.Mail.MailMessage are RFC 2822 compliant?

  • Hi ChKsh,

    Thank you for posting here.

    You can develop the email validation using Regex.

    For example.

    public static bool IsValidEmail(string email)
        Regex rx = new Regex(
        return rx.IsMatch(email);

    Here are two related references you can check.

    1. Validating an email address 
    2. Best Regular Expression for Email Validation in C#

    Hope it could be helpful.

    Best Regards,
