I am an end-user, rather than an email or system admin, but I have a
decent understanding of smtp, a little understanding of spf, and a
SLIGHT understanding of srs. One thing thats not clear to me in the SRS
explanations is whether the end user should ever see the rewritten
return path in the from field, and, if not, does it depend on some
system to remove or hide it.
The reason I ask is: I get a fair amount of email at my Verizon wireless
SMS (text message) cell phone address - alerts from different sources,
notification of work assignments, etc. And some of them come in with a
weird email address - for example:
SRS0=HrNdli=BZ=ds43.reliablehosting.com=nobody@kronhead.com. Generally,
these get forwarded to my phone from other addresses I use - I don't
remember exactly how this example was routed, since I have changed a lot
of things to try to get rid of this, and to solve some non-delivery
problems.
When I asked Verizon Wireless if they were familiar with SRS, and
whether they have implemented support for it - or if I was seeing this
because they had not, or because of a bad header from the sender
perhaps, their answer was "Verizon Wireless does not implement
anti-'spoofing' technology for use with our devices. In addition, we are
only able to provide information regarding features that are currently
available from us." Basically, a non answer.
Now, a newer message from the same source showed up correctly on my
phone. I don't think I changed anything in the routing - perhaps Verizon
did change something. And I should mention that I cannot see headers on
the SMS messages, so its hard to figure out whats going on.
But, my basic question is: should an end user ever see this kind of
address - can any of the scenarios of support or non-support in a
forwarding chain cause this - or is it dependent on the final receiving
system to hide these? Or is this normally only shown in smtp headers
that a user normally does not see?
