I'm having a lot of problems with GMail delivery due to lack of "one-click unsubscribe" -- however that is quantified, which is not clear.
In particular, there is an issue with the fact that Google ignores dots in email addresses. So I have many (MANY!) subscribers who try to use the List-Unsubscribe header target, but because they are subscribed as "idiotsubscriber@gmail.com" rather than "idiot.subscriber@gmail.com" (which they have since changed their sender to) they get a reject that they are not subscribed. These people are also far too unobservant to read the footer of every message that reads "You are subscribed as idiotsubscriber@gmail.com".
Is there any way to provide personalized List-Unsubscribe header links, or have Mailman ignore dots in gmail.com addresses... or... anything? I'm finding reported spam percentages in the Google Postmaster Dashboard exceeding 0.1%, which causes massive delivery blocking to GMail-based subscribers.
While I would gladly ban everyone who uses gmail, that sadly accounts for about half of the Internet today and would be incredibly unproductive.
Thanks, --Jered
