Because of your 'fire and forget', you are disposing of the mail message immediately; that may be affecting you. Also, you're not disposing of the mail client. You should put the entire operation into the "fire and forget", including the creation and disposal of SmtpClient. Something more like this:

FireAndForgetTask(async cancellationToken =>
{
                using(var smtp = new SmtpClient
                {
                    Host = "myhost",
                    Port = 587,
                    EnableSsl = false,
                    DeliveryMethod = SmtpDeliveryMethod.Network,
                    Credentials = new NetworkCredential("myemail", "mypass"),
                    Timeout = 50000
                })
                {          
                    using (var message = new MailMessage("myemail", destMail)
                    {
                        Subject = subject,
                        Body = mailBody,
                        IsBodyHtml = html           
                    })
                    {
                       await smtp.SendMailAsync(message);
                    }
                }
}
