So, I have a node 7 mode 8.2 Ontap all of a sudden can no longer reach the mail relay to send autosupport emails. I've checked DNS, IP routes, traceroute etc - all good - nothing has been changed on the filer, when i trigger the autosupport it is showing autosupport it is triggered in /etc/messages files but unable delivered. I am using smpt option. I also checked the smpt server is working as it is delivered to mail from other hosts. I looking for telnet command to check the port access from netapp towards mail host 25,. Please help with commands,.
Thanks in advance
