Direct Reply setup


Hi all
I’ve setup direct reply in Email Tab.

When i get email from rocketchat i see that reply_to fiield looks like “chat+bwqcuebcu@uknown_domain._om”
If i try to direct reply to this email actually it fails with error "Host or domain
name not found. Name service error for name=uknown_domain_com
type=A: Host not found

Why rocketchat generate domain in this way?
From field looks good (

Any thoughts ?
Thanks in advance
