HELO smtp.doma.com

220 MX.domain.com 

MAIL FROM: <user@domain.com>

Hello, 

May I know what are you trying to do or achieve with our device?? Are you using the latest firmware for the RUT950? 
Could you try updating the firmware to the latest one you can find the link here: 
RUT950 Firmware Downloads - Teltonika Networks Wiki (teltonika-networks.com) 

Regards,
Jerome
