Subscription cancellation request misinterpreted?:
I just noticed that a user attempted to unsubscribe an address by
sending an email with that address in the "From" field, and a second
address (presumably his new address) in the "Reply-to" field (I keep
copies of all subscribe and unsubscribe emails). Sounds reasonable,
but Letterrip attempted to unsubscribe the "reply-to" address rather
than the "from" address. That doesn't seem right.
Many mail list managers ignore the From header and use the
Return-Path header instead. Perhaps it's because From can be so
easily spoofed.**
I often use aliases when I have to provide an email address at a web
site in order to complete a transaction. This gets the alias address
onto their mailing list. When I try to unsub, using the alias as the
From address, I typically get back a Failed To Unsubscribe which
indicates it tried to unsub the Return-Path address. Bummer. As a
result, I sometimes telnet to their list server to unsub.
In your case, was the Reply-To address the same as the Return-Path?
**
I confess to more than once unsubbing others from mailing lists when
their dad-blasted autoresponder caused a loop which posted to the
list to which their auto-responder replied again and again. After the
40th or 50th such email, I have taken the law into my own hands and
sent an unsub message with the From address of the offender. In most
cases this no longer works and I end up unsubbing myself as the list
server used the Return-Path address instead of From. So I don't do
that any more.
It may very well be that ignoring the From address is in fact a
security feature preventing people like me from unsubbing others.
