here are 2 options:
1. look for a pop server that has the "allow relay from an IP that
connected to the pop server in the last 15 minutes" feature. i know
there are sites that use such setups. all u need is for the pop server
to update a hash map where sendmail is configured to look up for valid
IP addresses, using its normal "allow relay from a list of IPs" feture.
2. support a 'secret' field in the mail headers, where if it exists in a
letter, sendmail will allow mail relaying for this email letter. then
have your travelling salesmen (err, traveling managers) set their email
clients to send this field in each letter. also, make sure to filter
out this field before actually forwarding this letter.
this solution requires some understanding of sendmail.cf and rewerite
rules, but maybe someone already implemented it.
and after u get this working, let me know - i want to set it up as well
somewhere, and i was just too lazy to do that so far ;)
