We have SBS 2008 on premises. One of our Line Of Business applications has the capability to create marketing campaigns and send emails to multiple clients through our Exchange server. There could be up to 1000 emails going in one batch and this could be 2 or 3 times per month.
I have been warned that this may cause our server to be blacklisted as a source of SPAM. Is there any way I can prevent this from happening? I have full access to our domain DNS records and can make changes as necessary but I want to know if this is feasible.
