How to change device name, without restart ? Sending email using SMTP issue!

Hi there,

I am trying to send email using SMTP send mail , when i send an email i can see in email headers the name of my computer , do you know if there is a way to hide that or change it using the SMTP send mail Advanced, I tried but failed if you can help me out I would appreciate it

Thank you

Edit: I tried to change it via powershell it worked, but it needs a restart for that new pc name to be affected. is there any way to change it without a restart ? I tried to set in the Advanced headers a message id but it says there are 2 , i don’t see an option to edit that name in Openbullet 2 for Web , could you please help me out thank you.
