I am trying to allow vendors and clients to access my portal and I get an
error when sending the email invitation ONLY to external domains.
When configuring a domain user for access, the email delivers properly.
Outside users are being setup a LOCAL users on the SPS server.
I can telnet between both my Exchange and my SPS servers. I have added my
SPS's internal AND external IP to the allowed relay list on Exchange. I have
also tried configuring a local SMTP server on SPS with a smarthost setup to
try to delivery via Exchange (it will attempt llocal delivery first). I am
still not able to invite users with external domains (ie.e, yahoo.com)
Please advise.
