I have instslled Mozilla Thunderbird in order to redirect a large number of emails. Redirct extention works but there is a problem. Original senders name and email subject line retained but date is latest date received at redirected site. Need to have original date and time retained. I saw a post on another site that original date can be preserved. Anyone now how to do this? Urgent. Large batch of 150 or so emails almost useless with date sorting. Thanks.
