      This seems like an odd thing to believe.

          email admin who doesn't know email basics

          This makes me question the admins qualifications. Maybe their new and still learning their role?

            No kidding. We are seriously questioning the qualifications of the person who brought this up.

              So the admin was saying that the Email and mail from needed to match?

                No, that the from and mailfrom fields need to match in the header. Makes no sense. Clearly doesn't grasp how email works.

                  Yeah, that doesnโ€™t make sense.

                      We are pretty sure that they are out of their minds. I can't believe that they thought that we would buy this.

                        https://tools.ietf.org/html/rfc5322#section-3.6.2

                        Originator Fields

                        The originator fields of a message consist of the from field, the
                        sender field (when applicable), and optionally the reply-to field.
                        The from field consists of the field name "From" and a comma-
                        separated list of one or more mailbox specifications. If the from
                        field contains more than one mailbox specification in the mailbox-
                        list, then the sender field, containing the field name "Sender" and a
                        single mailbox specification, MUST appear in the message. In either
                        case, an optional reply-to field MAY also be included, which contains
                        the field name "Reply-To" and a comma-separated list of one or more
                        addresses.

                        from = "From:" mailbox-list CRLF

                        sender = "Sender:" mailbox CRLF

                        reply-to = "Reply-To:" address-list CRLF

                        The originator fields indicate the mailbox(es) of the source of the
                        message. The "From:" field specifies the author(s) of the message,
                        that is, the mailbox(es) of the person(s) or system(s) responsible
                        for the writing of the message. The "Sender:" field specifies the
                        mailbox of the agent responsible for the actual transmission of the
                        message. For example, if a secretary were to send a message for
                        another person, the mailbox of the secretary would appear in the
                        "Sender:" field and the mailbox of the actual author would appear in
                        the "From:" field. If the originator of the message can be indicated by a single mailbox and the author and transmitter are identical, the "Sender:" field SHOULD NOT be used. Otherwise, both fields SHOULD appear.

                        Note: The transmitter information is always present. The absence
                        of the "Sender:" field is sometimes mistakenly taken to mean that
                        the agent responsible for transmission of the message has not been
                        specified. This absence merely means that the transmitter is
                        identical to the author and is therefore not redundantly placed
                        into the "Sender:" field.

                        The originator fields also provide the information required when
                        replying to a message. When the "Reply-To:" field is present, it
                        indicates the address(es) to which the author of the message suggests
                        that replies be sent. In the absence of the "Reply-To:" field,
                        replies SHOULD by default be sent to the mailbox(es) specified in the
                        "From:" field unless otherwise specified by the person composing the
                        reply.

                        In all cases, the "From:" field SHOULD NOT contain any mailbox that
                        does not belong to the author(s) of the message. See also section
                        3.6.3 for more information on forming the destination addresses for a
                        reply.
