I have a cluster setup, 1 Mail/LDAP and 1 MTA/Proxy. The MTA/Proxy failed due to a HD issue, therefore I had to reinstall CentOS on the system. I don't have any backups of the MTA/Proxy so I'm wondering if anyone knows the most efficient way to go about getting this back and working.
I know that backing up the account info on the Mailstore then going through fresh cluster install and restoring the accounts would work, but I was wondering if it's possible to reinsert the MTA/Proxy into it's old spot without backups. Any ideas?
