FEATURE(access_db), maybe combined with one or more of the other relay_*
features. The problem here is that relaying permission based on MAIL FROM:
is open to spoofing, so I'd combine it with some sort of IP based access
control. Simple enough if the user dials in from a static IP, a bit more
difficult when dynamic IP's are involved (access_db allows network addresses
and IP addresses). Maybe take a look at tcp_wrappers (but then you'll have

Another option is "POP before SMTP", but I don't know of any patches/setups
sendmail. Basically, the user dials in to retrieve his/her mail through POP,
and this triggers a rebuild of the MTA access database to allow this user
