I have a nagios server which is already configured by someone. Low disk space alerts are also set on my company email. Our company has mail server xyz.com. Before some days someone has made some changes related to security in mail server xyz.com.And since at that time I am not able to receive mails on my ID [email protected]. I have asked security team about that, they told me that only port 1025 is open so change port number into you nagios server. and you will get alert mail from your nagios again.
Can anybody help me that how can i change port on nagios ? As I am new for nagios, please also give me the file name in which i need to replace port number to get alert mail.
Thanks,
