In Linux, how can I check whether the email system has been installed successfully?

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

Check whether there is

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.

If the JDMAIL_ROOT settings are correct, the jdmail service process still cannot be started. For www.britepic.org, please record the operating system version and contact the Customer Service staff of jindi mail to help solve the problem.
