don't know whether it is greylisting. but all my posts (including the
previous two) are on the list if I look through webpage. I checked the
preference of my subscribtion, it enabled to send me the post I send,
but just can't get it in thunderbird. something wrong? how to solve this
problem? I don't know my post appears on the list or not. But it is on
the web archive

At least some of the Redhat list servers use greylisting. It
appears, looking back through your posts to the list, that your ISP
uses several different servers to deliver mail to the list. For
example, here is a list from 5 of your messages to the list showing
which of your ISP's mail servers connected to which of Redhat's
list servers:
fra-del-03.spheriq.net [195.46.51.99]) by mx1.redhat.com
fra-del-01.spheriq.net [195.46.51.97]) by mx3.redhat.com
lon-del-03.spheriq.net [195.46.50.99]) by mx1.redhat.com
lon-del-03.spheriq.net [195.46.50.99]) by mx3.redhat.com
lon-del-02.spheriq.net [195.46.50.98]) by mx1.redhat.com
If your ISP uses a pool of servers to deliver mail where a different
server can attempt to deliver mail each time a delivery is tried
then greylisting can effectively block your messages until the same
server at your ISP tries to deliver a second time to the same
Redhat list server. You would have to be able to see the logs at
your ISP's above listed mail servers in order to be sure this is
the problem though.
Greylisting does have a mechanism to allow mail to get through in
this type of scenario but you'd have to discuss this with the
Redhat mail server administrator(s).
