I have a new Exchange 2010 that send email using its own SMTP. We are using Mcafee (formerly MX Logic) to scan and filter emails. I have few emails (for example form Craigslist) that are bouncing back. I have the feeling I should have both incoming and outgoing configured to use Mcafee servers. I got the incoming part covered, I need to configure the outgoing emails to relay to Mcafee.
Thanks for your help.
