Hi,
Are you sure you're using smtp? If you have a local MTA, you don't need to use smtp. It's indeed best not to use SMTP in these circumstances because using the local MTA is more reliable.
If you've postfix correctly installed locally, remove all of the SMTP settings from your config.
try :
grep -ril '192.168.2.102' /etc to see if there are any other places it might be referenced.
This error message is coming from postfix, and doesn't really have anything to do with observium beyond postfix being on the same system. Probably there's a smarthost line or something somewhere in the postfix config you've missed. Grep will find it!

Hey all, we upgraded our Exchange server and now it has a new address. I changed the old address, xxx.xxx.xxx.102 to the new address, xxx.xxx.xxx.105 in config.php and Observium still sees the old address.
Nov 6 12:00:19 Observe postfix/smtp[27371]: connect to 192.168.2.102[192.168.2.102]:25: No route to host
The new address was also changed in /etc/postfix/main.cf. I've rebooted the server a couple of times but no joy. I must be missing something really simple here but I don't have a clue what it could be. Is there still another location where I need to change my new Exchange server's address?
Thanks,
