Not for to use this list but i do have a gmail account as spamcatcher
for a publicly visible mail address. I never use the web interface
though but use Thunderbird to handle that account. So i do not see fancy
lines or high value folders or am using stars. So far Google does handle
spam correctly and I do not have to search that often in the spam
folder. I recommend this for all gmail users.

I do run my own MTA (three of them actually) and noticed a rejection by
gmail the moment I got IPv6 and forgot to set reverse DNS for it. So
rDNS is a thing for gettingaccepted by gmail.


Grtz.
