Hi, I'm part of the IT department for my company and have been trying to help someone register SAM that was downloaded from here. The emails from NREL for SAM registration were automatically rejected by our email protection service. When we looked deeper into it, it seems like the emails originate from a blacklisted IP address (149.72.154.232) that is associated with spam according to the blacklists SORBS NEW, SORBS SPAM, SPAMCOP, and SWINOG on MX Toolbox. As a result of this automatic rejection, we don't receive the registration codes needed for activating SAM outside of the trial period.
Regards,
Max
