Here's the situation I'm facing. I need to set up an email account. Let's say that it's . The sender or the email server does not allow us to have this address in 'From'; at the moment, I can only send emails using . I called my ISP, but they're no help. I spoke to a couple of different consumer supports, but they have no idea what to do about this. Is there any workaround? Is there a way to use as the sender address while I use an email client like Mozilla Thunderbird and Outlook Express?
