Hi All, I'm using Mozilla Thunderbird to send emails. It's a great program, but I would also like to use MSGTAG, an automatic read notification program, to make sure my messages are received. I can get MSGTAG to work with Outlook, but not Thunderbird. Has anyone came across this problem, and more importantly, managed to find a fix? I've checked the ports and they seem okay. If you can't help, perhaps someone can recommend an alternative to MSGTAG? Thanks in advance. Bob Kelly
