Returns a set of flags indicating which authentication methods are supported by the server.

Return Value

A set of flags indicating which authentication methods are supported by the server, or None if Hello method has not yet been called or if the server does not support EHLO command (i.e. the server is not ESMTP enabled).

Exceptions

Example

This sample lists all authentication methods supported by the SMTP server. SMTP servers do not support non-SASL methods, thus only SASL methods are checked.

[C#]
// To use the code below, import these namespaces at the top of your code.
using System;
using MailBee;
using MailBee.SmtpMail;

// The actual code (put it into a method of your class)

Smtp mailer = new Smtp();
mailer.SmtpServers.Add("mail.domain.com");
mailer.Connect();
mailer.Hello();

AuthenticationMethods methods = mailer.GetSupportedAuthMethods();
if ( (methods & AuthenticationMethods.SaslLogin) > 0)
{
    Console.WriteLine("SASL LOGIN");
}
if ( (methods & AuthenticationMethods.SaslPlain) > 0)
{
    Console.WriteLine("SASL PLAIN");
}
if ( (methods & AuthenticationMethods.SaslCramMD5) > 0)
{
    Console.WriteLine("SASL CRAM-MD5 (secure)");
}

mailer.Disconnect();
