How to test a POP server by using telnet
What you need
The host name of the POP server (for use in the telnet command)
The POP user name (for use in the USER command)
The user’s POP password (for use in the PASS command)
Encryption
For added security, you can encrypt your POP connection. This requires that your server supports SSL or TLS and that you have access to an SSL/TLS client program, for example OpenSSL, to use instead of telnet.
As the port number normally is 995, an example OpenSSL command would be openssl s_client -connect pop.example.com:995 -quiet. (If you would like to see the public key of the server, as well as some other encryption-related information, omit -quiet.) The server should then start a POP session, displaying a greeting such as the +OK InterMail POP3 server ready example below.
What to do
The DELE command flags messages for deletion. Use it only if you want to delete mail.
The initial telnet: > symbolises your shell prompt.
telnet: > telnet pop.example.com pop3
telnet: Trying 192.0.2.2...
telnet: Connected to pop.example.com.
telnet: Escape character is '^]'.
server: +OK InterMail POP3 server ready.

server: +OK please send PASS command
client: PASS MyPassword
server: +OK MyUsername is welcome here

( 3 / 1414 )儒略日的計算
設Y為給定年份，M為月份，D為該月日期（可以帶小數）。
若M > 2，Y和M不變，若 M =1或2，以Y–1代Y，以M+12代M，換句話說，如果日期在1月或2月，則被看作是在前一年的13月或14月。
對格裡高利曆有 ：A = INT（Y/100） B = 2 - A + INT(A/4)
對儒略曆，取 B = 0 More...

I first saw nsupdate mentioned on the devops-toolchain mailing list as a tool for dynamically updating DNS zone files from the command line. Since this definitely beats manual editing of zone files, I'd thought I'd give it a try. My setup is BIND 9 on Ubuntu 10.04. I won't go into the details of setting up BIND 9 on Ubuntu -- see a good article about this here. More...
