using AegisImplicitMail;
IConfiguration _config;
MimeMailer _oSMTPAIMClient;

public MessageSender(IConfiguration config)
        {
        public Task SendEmailAsync(string email, string subject, string message)
        {
                 _oSMTPAIMClient = new MimeMailer(
                        _config.GetValue<string>("Email:Host"), // (smtp.office365.com)
                        _config.GetValue<int>("Email:Port") //465
                    );

                     _oSMTPAIMClient.Credentials = new System.Net.NetworkCredential(
                        _config.GetValue<string>("Email:Username"),
                        _config.GetValue<string>("Email:Password")
                    );
                    _oSMTPAIMClient.EnableImplicitSsl = _config.GetValue<bool>("Email:EnableSsl"); // true
            _oSMTPAIMClient.SslType = SslMode.Tls;

            MimeMailMessage mailMsg = new MailMessage();
            mailMsg.From = new MailAddress(_config.GetValue<string>("Email:From"));
            mailMsg.IsBodyHtml = true;
            mailMsg.Subject = subject;
            mailMsg.Body = message;
            mailMsg.To.Add(email);

            _oSMTPAIMClient.Send(mailMsg);

           }

            private void compEvent(object sender, AsyncCompletedEventArgs e)
        {
            if (e.UserState != null)
                Console.Out.WriteLine(e.UserState.ToString());

            Console.Out.WriteLine("is it canceled? " + e.Cancelled);

            if (e.Error != null)
                Console.Out.WriteLine("Error : " + e.Error.Message);
        }
}

And... nevermind. When I rewrited it... it works! sorry.

Hi,

Maybe I'm doing something wrong ?

I've got:
host: smtp.office365.com
port: 587
EnableImplicitSsl: true (nor false) - same result
SslType: SslMode.Tls (nor Auto), for Ssl - connection is droped at all (it also automatically changes EnableImplicitSsl to true).

Adding attachment as Stream

I found that this feature does not work. It adds the attachment as inline only and all mail servers reject this.

var ms = new MemoryStream(<byte[]>);
var attachment = new MimeAttachment(ms, <file name="">, new ContentType("application/pdf"), AttachmentLocation.Attachmed);
mymessage.Attachments.Add(attachment);</file></byte[]>

Hi,

how can I add attachment as Stream?

The message is not sended
