If you are a white-collar engineer, often sitting in the office and sending and receiving emails every day, you can use the Linux operating system in the company, so you have installed the mail system in the Linux operating system, but do you know the installation is successful? In Linux, how does one check whether the email system is successfully installed? This article explains in detail,

1) check whether the smtp and pop3 services are properly started in Linux.

You can enter:

# Telnet localhost 25

If shown: 220 jdmail SMTP Service ready

This indicates that the smtp service is successfully started. If this information is not returned, other smtp services may have occupied port 25. Stop other smtp services first. Generally, the sendmail service is started by default and can be used as follows:

# Pkill-9 sendmail

# Chkconfig-level 2345 sendmail off

Disable the sendmail service.

If no prompt is displayed, return to the command prompt, indicating that the jdmail service is not started properly. Enter:

# Ps-ef | grep jdmail

  8. root 23593 23446 0 Apr22 ? 00:00:02 ./jdmail 

If these service processes are not started, check whether the JDMAIL_ROOT path setting in the startjd. sh script is correct.
