i just ran tests from mxtoolbox on our domain and received the following warnings:
SMTP Reverse DNS Mismatch: Warning - Reverse DNS does not match SMTP Banner
SMTP TLS: Warning - Does not support TLS
what can i do on the kerio server side to sort these issues out
i m looking to have a "hot spare" server setup at a colo... and was wondering the best way to get the data across to the colo machine from the "live" server... can i use something like chronosync, carbon copy clone to copy the data... or is there a better way.. and... which data should i be porting across so all i need to do is enable kerio on this machine and it is a perfect replica of our main server
and... even though this server will not be in use unless in an emergency (ie. our primary mail server goes down).... can i use the same serial number etc that we have for our primary mail server.. so that when it is called into action.... it is ready to rock?
thanks in advance for any help
To fix reverse DNS you'll need to get your ISP to add a reverse lookup record in DNS for your mail server. It has to be done at your colo ISP.
As far as the hot spare, search these forums. There is a lot of information. Nothing is 100% automatic but you can come close. Cloning solutions are good although not supported by Kerio because data can show up corrupted. Keeping the storage separate from the boot drive is good so that you can move it to another server.
Some issues such as IP address etc you'll need to work with if you have a second server.
A good practice is to have plenty of spare hardware to swap quickly, good backup AND a clone of everything.
