Sounds like you want SMTP-after-POP. I.e., users who successfully
authenticate via POP are allowed to relay via SMTP for some short
period of time. Look for "open-smtp" on www.qmail.org.

Now you're saying you want to allow relaying based on the From header
field? That's a very bad idea because some spammers (and realy
checkers) are aware of this method and forge their headers to take
advantage of it.
