We are currently running SmarterMail to host several domains. I would like to switch over and use SmarterMail as the backup MX server as well. I can follow the kb article for doing so, but my question is how can I prevent the backup MX server from accepting and queuing email for domains that are not currently hosting on our primary SmarterMail server? For instance we accept domain1.com, domain2.com, etc. I'm not seeing from the kb where I can prevent it from accepting email at domain3.com. Probably overlooking something... Thanks in advance,
