Hello Charles,
I want to know more details about the RFC which discuss on the
empty (null) envelope sender. Can you tell me the RFC number and from
where I could access the RFC ?
I ask because I found that one of my ISP's server will reject
emails with Return-path <>. This make me many inconvenience.
Maybe I could talk with my ISP after checking it in details.
Thanks in advance.
Kenneth
