Were the ones you sent to me returned?
I can see two possibilities why I wouldn't have seen or gotten them (assuming you have my address correct ..
One is if it doesn't have words in the subject field that make it stand out from the multitude of Spam I get it might be deleted. RE: ECN Forum or something Electrical in the subject field will catch my eye. I do look for emails with attachments before the Trash gets dumped too, but if an email has an embedded picture it might not be seen.
Another possibility is that you are on a server that was sending a lot of Virusses or spam at one time and it is blocked by our Mail Server.
To try and figure this out please send me something and tell me here in this thread that it was sent and when. I invite anyone else that wants to do the same thing.
