99.9% of my list problems involving subscribing by potential members is due to the "reply-to" area of their mailer being incomplete and 100% of this occurance is found in users using the Microsoft mail programs. Could somebody point me in the right direction on how to fix this problem so I can tell them? Right now I tell them to figure it out or switch to another email program because I refuse to run the program on my machines. However, the vast majority of my list members are at the lower third of the technically adept ladder and they find my suggestion to be pretty non-helpful. TIA for any help
