I would like send auto-reply mails to email addresses written in reply-to field. How this can be achieved?
Sample Mail Received :
from: abc@gmail.com
reply-to: def@gmail.com
to: ghi@gmail.com
date: Aug 31, 2020, 12:43 AM
By using the template and filter options I am able to send auto-reply e-mails to addresses written in from field (abc@gmail.com in this case). But I am not able to figure how to send auto-reply to addresses written in reply-to field (def@gmail.com in this case).

Google does not support this.
It is possible write a Google Apps Script, possibly/probably including the Gmail API , to generate an email that has the appearance of being an auto-reply (a "pseudo-autoreply"). There are many precedents for this. However these do not have the character of auto-reply emails, and they have some inherent limitations.
