Outbound SMTP Email alerts from Hikvision NVR

[gabemcg 0]

Setting up email alerts from my Hikvision NVR... not working.

 

Sniffed the traffic leaving my network, and the NVR is sending a HELO command with 'dvrdvs' as the hostname.

 

The mail server rejects the connection because the HELO command does not have a fully qualified hostname.

 

I logged into the NVR via telnet, and set the hostname to be a fully qualified one, and now it works.

 

Anyone else seen this issue? Any way to set the hostname via the GUI? If not, how can I set the hostname via the CLI so that it is preserved on reboots?

I never had a problem with SMTP on any of the Hikvision devices I have used it (DVR, NVR and IP camera). I use mostly gmail for email sending. Maybe the email server you are using is being a little too picky?

More specifically:

 

550 R1: HELO should be a FQDN or address literal (See RFC 2821 4.1.1.1)
