Hi All,

I am unable to config specific smtp mail settings. Get error message as Warning: Unable to validate mailserver "smtp.******.net:2555". Reason: Weird server reply.

Kindly advice on the below commands

RUH-PS-DM5000H::> event config modify -mail-server smtp.******.net:2555 -mail-from ruh.DM5000@alerts.******.net

Warning: Unable to validate mailserver "smtp.******.net:2555". Reason: Weird server reply.
Do you want to continue? {y|n}: n

Hi,

Looking at the command: 'event config', it seems you are manually entering 'smtp.******.net:2555' as smtp server, why is there ':2555' ? Doesn't make any sense.

SMTP mail server are usually in this format:
smtp.yourcompany.com (smtp is nothing but your mailhost, in your case 'smtp' is your mail I believe, only you can confer that)
or,
mailhost.abc.co.whatever
or,
mailhost.abc.com

Just try configuring using "smtp.******.net" as smtp server.

Use this command:

::> event config modify -mail-server smtp.******.nets -mail-from ruh.DM5000@alerts.******.net

If you still get error, then follow the standard SMTP troubleshooting steps:

I've edited the posts here to remove the specific server name.

In doing so, I noticed that the send to email address (it.systems@*****.net) is missing the last letter of the domain, unlike the other entries in the output you've shared.

In addition to the above suggestion by @Ontapforrum, you might check the server addresses one more time.

You're welcome. Unfortunately, we cannot use GUI, but CLI should be straight forward if you use that command.

Hi,

We tried the command without the port number 2555 and it works without error.

But customer is looking for the custom port number 2555 in the alerts config, Hence we conclude that Netapp will not support custom port number 2555.

Kindly advice

Hi,

All alerts and notification are working after removal of the custom port in the smtp command.

Thanks for the support
