I used to use the + system but ran into too many issues of it not being accepted and it seems some are smart enough to strip off the + and everything after.

I moved to wildcard forwarder on my own domain so that *@mydomain.com get forwarded to my main email account. This gives me all the tracking I want and I can ban addresses if needed.

That still gets me the zero overhead and practically infinite addresses with none of the downsides of gmail--and I can easily change my main email account as an added bonus.
