No data available for Mail Queue on Linux/AIX/Sun Solaris in SSH/TELNET mode
Problem:
No data is displayed for the Mail Queue on Linux, AIX, or Sun Solaris servers when monitored via SSH/TELNET mode in Applications Manager.
Solution:
- Login to the server using SSH mode with the same credentials configured in Applications Manager.
Run the following command to check the Mail Queue:

mailq
- If the mailq command is not found or returns an error (e.g., Command not found), it means the command is not installed.
- To resolve this, install the required package containing the mailq command. The installation process may vary depending on your operating system.
- After installation, re-run the mailq command to ensure it works as expected
