Schedule Emails 4 Future delivery - outlook hangs send/recie

Hello, I have emails I need to respond to everyday from 10-15 different popular email clients. The emails need to have a delayed response scheduled 1-2 days delayed response. I need to have responses to all the emails and they can not look like an auto response and it cant respond right away. So a client will email me and the email would be put in a quey to automatically respond in a day or 2 so the email accounts will no longer need to be monitored. Is there a way to do this? I have set up outlook with Auto Reply Manager and I wish it would work but outlook 2007 keeps freezing and hanging in send/recieve and all my delayed emails are not going out. If you can solve with a solution I already have not tried u will win my heart. Let me know How long it will take and your price for the "how to" information or the software or solution. Thankx 4 reading Barry
