Add email "opened" tracking gif function to WorldClient
Add email "opened" tracking gif function to WorldClient. Something like what CritSend and other smtp relay services provide. A column in WorldClient could show the status of the message to see if it was opened by the recipient. I believe they are doing this via a hidden gif that is embedded in the email and tracked when accessed on the mailserver. Would be great for people using mdaemon for mailing lists but also good for day to day usage.
I have merged several ideas together. This will be considered for future versions of MDaemon.

Is this not the reason that email clients now include features to prevent automatic opening of HTML images? The feature in World Client is turned on by default.
I don't see why MDaemon should include options to send tracking information where it is actively blocking such requests in its email client.
