[Mailman-Users] [discuss] configuration of the maillist server from 1net.org

[willi uebelherr]

Dear friends,

now i think, it is clear. The feature "duplicate suppression" is a fix 
mechanism. I will wait for the answers of the people from the 
mailman-users list, what the say about. But in Gmail with a user 
configuration never i can resolve the problem.

The mailman server never want to support the change of message-id. And 
as a user never i can do it. Only with a second user subscribing. My 
next alternative is to use GMX in Germany or any other non-non-neutral 
mailserver.

I ordered the mails in inverse chronical order.

many greetings, willi

No, you cannot turn off duplicate suppression.

Gmail follows the RFCs and treats the Message-ID as globally unique for 
a particular version of the message.  According to RFC5322, changing the 
Message-ID is the correct way to identify a new revision of the message. 
In regards to the added headers, it states:

The addition of such header fields does not change the identity of the
message and therefore the original "Message-ID:" field is retained. In 
all cases, it is the meaning that the sender of the message wishes to 
convey (i.e., *whether this is the same message or a different 
**message*) that *determines whether or not the "Message-ID:" field 
**changes, *not any particular syntactic difference that appears (or 
does not appear) in the message.

In other words, if you consider the message sent from the mailing list 
to be a different message, change the Message-ID. Keeping the Message-ID 
signals that it is the same message, and Gmail will suppress it as a 
duplicate.

It should not affect message threading or other functions.  (Threading 
is based on headers referencing previous messages, which are not 
changing. Changing the ID on the new message doesn't affect any of those 
headers.)

If you don't want to change the Message-ID, you can subscribe another
address to the list to get all of the messages.

Dear bkennelly,

i thought, that gmail use the message-id for compare. But the mail i 
send is different to the mail i receive. The mailheader is extended. And 
this information is always necessary for me.

To change the message-id is a bad way because the message-id are used 
for thread ordering in the mail directory. And many internal functions 
are working based on the message-id.

My primary question goes to the possibility, how i can define or 
enable/disable this delete function in this account.

Gmail only stores one copy of each message in your account.  If you sent 
the message, you already have a copy and the incoming copy is recognised 
as a duplicate.

If your mailing list software has the option to change the Message-ID 
when re-sending messages, Gmail will recognise the returning message as 
a new version and you will get it in your Inbox.

Dear friends,

the gmail-server blocked email to my account. Not as spam. No, as any else.

If i send a mail to a maillistserver for distribution, i want to receive 
this mail from the listserver. But google stopped this mail without my 
request and without any information to me.

In the mailman-configuration i can set this option. But then, it have to 
work transparently and never i accept any hidden mail deleting.
