If the forwarding user sends a message to himself, he gets the
message unharmed, just like he would get any other message.
Will he?
If a message bounces (for instance because the iser forwarded his
pobox address to his gmx.net box which happens to be full), the
following will happen:
1. alice(_at_)yahoo(_dot_)com sends to bob(_at_)pobox(_dot_)com
bob(_at_)pobox(_dot_)com sends to bob(_at_)pobox(_dot_)com
2. pobox rewrites this message as:
bob(_at_)pobox(_dot_)com => bob(_at_)gmx(_dot_)net
dito
3. Gmx bounces it:
<>@gmx.net => bob(_at_)pobox(_dot_)com
right
4. pobox forwards it again, replacing original sender:
bob(_at_)pobox(_dot_)com -> bob(_at_)gmx(_dot_)net
...=> ad infinitum.
Indeed. We don't need alice.
Alice delivers to pobox.com without any problems.
I think the problem (in this example) is at pobox.com and/or gmx.net
not with alice(_at_)yahoo(_dot_)com; the problem should be found, recognized and
solved by pobox.com and/or gmx.net
If the message author is made aware, he/she can take action (send
message again hoping that problem is solved; use a different
communication channel such as the phone; ...)
Please publish your phone number, pager, or whatever other technology
I can use to reach you 24/7. But don't expect me to do the same.
IOW, you cannot rely on this to work and thus have to fix forwarding.
cheers,
Alex
