Please check following :

• Try to verify whether the host name/ip of the SMTP mail server is correct or not.
• make sure there is no host entry for the provided ip or hostname in /etc/hosts file.
• Telnet the SMTP mail server see whether if the connection can be establish or not. Generally in corporates they white list other then default port ( 25 ). Check with your IT team and confirm the ip and port again.

• There can be other cause if IPv6 is getting used, Please try connecting by adding following jvm argument and try connecting with IPv4 argument as below :

  -Djava.net.preferIPv4Stack=true
