You can only archive incoming e-mails via autoforward, not drafts and not outgoing email (unless you use their mailservers, which is something completely different). If I want archiving for my e-mails, I have to give up my account credentials. You could actually do sufficient mischief with the archived e-mails, you don't need the account credentials in the first place. That sucks, but it's not their fault, this kind of service is inherently insecure.

Now, if you can demonstrate that this particular company has a particularly unsafe way of storing the passwords or the retrieved e-mails, then you're getting closer to having a valid point.
