Milter-greylist

Hello,

I wanted to test this very interesting method and this milter, but I
suddenly remembered  that our users subscribe regularly to mailing lists,
which mails get caught with the spam regularly. What about milter-greylist
behaviour with such mailing lists ?

the sender adresses are really various - generally, they will be technology
vendors, such as Dell, Texas Instruments, who use to send informations about
their products this way, several IT mailing lists in the open-source world,
local partners too - well, I don't remember all the lists, but they are
corporate ones, which MAY sometimes use standard bulk mailers (I mean,
corporate bulk mailers) such as xmr3 (http://info.xpedite.com/) which which
send bulk mail for normal companies, and spammers too.

Some time ago, I also noticed one very official company - it must have been
the European Space Agency - which incorporated our standard business adress
cedrat@... (the one that we NEED to show all over the world in order
to be contacted, and which receives all possible spam) in a mailing list in
order to inform its partners of some event.

for example, here are the two last adresses who sent normal informational
mail :

Power_Technology@...
EDN@...

they belong to the same company, and the mail was caught because the MTA :
mta.email.reedbusiness.com  was registered as a bulk mailer in the
FIVE-TEN-SG database. But one of our engineers does want to receive such
emails

We have a real MTA sending spam here. Greylisting is not helpful to
fight aginst that. Blacklists are the right tool.

Hello,

I was wondering : if one subscribes to a normal mailing list manager such as
mailman (for example subscribing to one of the lists from lists.gnu.org),
how will the mailing list SMTP server behave when hitting milter-greylist ?
Did anybody already carried out such an experiment ?

Best regards

Why should it hit milter greylist? At least the mailing list managers
I know use the local mail transport agent to deliver e-mail. So it's
the MTA which "hits" milter greylist. And it should be able to handle
that because it will otherwise lose e-mail all the time.

	Kind regards
