Ah Ha, thanks, Joseph! Someplace I forgot to look. On the SMTP Out tab, it is set to use the one specific IP. I assume I'll need to change that to Use the Domain's IP. I checked a handful, and on the Domain Edit screen, Technical tab, they do all appear to be set to the main IP except for the one, which is what I want.
This does bring up another question however: Once I set it to use the Domain's IP on the SMTP Out tab, will SM still use the primary NIC IP as the default when new domains are created, or will I need to go in and select it manually?
Thanks again.
