Hello,
I am interested in opinions on the feasibility of transmitting DSN requests
by means of message headers rather than SMTP (as RFC 1891 describes). The
benefit of using headers would be that they pass through non-supporting
MTAs, while the SMTP method is thwarted upon encountering an MTA that knows
nothing about the DSN extension.
I realize that only a subset of the request functionality described in RFC
1891 may be possible. The first thing that comes to mind is that headers
would not provide an easy way to do per-address requests.
Is this an idea worth pursuing or one doomed to failure?
Thanks,
Mark
