Hi All, I have a domain name where all the emails sent to it is placed in my email server. I randomly provide all my contacts with their own email address: eg mozilla@domain.com Thunderbird also allows me to customise the From address. Now, when I want to reply to one of these emails, instead of making the From the same as the To address of the original email (mozilla@domail.com), it has the Account email address (account@domain.com). Quite often I forget to check the From address and send it. This has been confusing for the recipient, and myself, so say the least. I've check the internet, including this forum, and it seems to be a common complaint. However, I've found no solutions. Surely it can''t be that hard to make the reply From address the same as the To address of the original email!
