Description Alex Wielhouwer 2014-01-13 16:34:35 UTC
I have narrowed the issue to the following example:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Mail;

namespace OnCue24
    class Program
        static void Main(string[] args)
            Program a = new Program();

        public Program()
            Mailer("<html><body>This is a test<br /><img src=\"cid:logo\"></body></html>", "Test message", "project", "test", "_fullpathtogiffile_",
                "image/gif", "_targetemail", "_smtplogonid", "_smtplogonpassword", "_smtpserver", "_senderemail");

        public void Mailer(string body, string subject, string project, string path, string attach, string attachtype,
            string useremail, string sendid, string sendpw, string sendsrvr, string sender)
            SmtpClient smtp = new SmtpClient(sendsrvr);
            smtp.Credentials = new System.Net.NetworkCredential(sendid, sendpw);

            MailMessage m = new MailMessage();
            m.Subject = subject;
            AlternateView html = AlternateView.CreateAlternateViewFromString(body, Encoding.UTF8, System.Net.Mime.MediaTypeNames.Text.Html);

            if (!String.IsNullOrWhiteSpace(attach))
                LinkedResource logo = new LinkedResource(attach, attachtype);
                logo.ContentId = "logo";
                logo.ContentType.MediaType = attachtype;
                logo.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
                logo.ContentType.Name = logo.ContentId;
                logo.ContentLink = new Uri("cid:" + logo.ContentId);
            m.IsBodyHtml = true;

            m.From = new MailAddress(sender, "displayname");
            m = null;

on Windows 7 using Latest DotNet the embedded image is displayed correctly.
on Ubuntu 12.04.3 (Mono the image is not present and a box with an x inside is shown instead, like a web page displays when it cannot find the image. 
The same image gif, logon userid, smtp server and executable is used in both tests.
