For my SMART_HOST I use an MX record, that way I can prioritize the servers.

define(`SMART_HOST', `smtp:outgoing-sm')

outgoing-sm             IN      MX      10 mailgw3.
outgoing-sm             IN      MX      10 mailgw4.
outgoing-sm             IN      MX      20 mailgw2.
outgoing-sm             IN      MX      30 mailgw1.
