You are correct. That would most certainly be foolish.

No, that would be a bad idea since the "From:" field is controlled by the
user. You would quickly find yourself bein used as "Spam Central
Station." Anyway, you're looking for something called "Roaming" which
enables relaying for a set period of time after someone authenticates
successfully via POP3. The only problem with this is if your customers
email client attempts to send mail before it logs in to POP3 to receive
it.
I'm not sure if this feature is supported in plain-vanilla qmail, but it
can be accomplished using vpopmail. Check out the FAQ at
