We are planning to use multiple smarthosts for failover purpose, so if one is unavailable Exchange route the messages to other one.
Following is details our of messaging infrastructure:
a) Only one Exchange 2003 server, single bridgehead and routing group.
b) Smarthost - 1
c) Single SMTP connector on Exchange with 'cost' value 1.
What would be the best possible solution, so Exchange do the automatic failover to smarthost?
If we use single SMTP connector with 2 smarthosts entries seperated by semicolon (;) would it do failover or load balancing?
Is there any difference in using Semicolon (;) or Comma (,) to seperate multiple smarthost on single SMTP connector?
Thanks in advance,
