1. I have 2 backend servers and one proxy-cum/mupdate server. The 
password comes as clear text over the network (unsafe) to proxy. Then I 
am forced to use TLS between the backend and frontend servers... This 
network is safe and i dun want the overhead of ssl... Is there a way to 
overcome this
2. When i use SSL in the backend server, it asks for a password
Enter PEM pass phrase:
I dun want to enter the password every time i restart master... Is there 
a way
I generate a the CA and certificates with this.
openssl req -new -x509 -keyout CAkey.pem -out CAcert.pem
openssl req  -new -keyout mailkey.pem -out mailreq.pem  -days 360
cat mailreq.pem mailkey.pem > mail.pem
openssl ca  -policy policy_anything -out mailcert.pem  -infiles mail.pem
