Actually it is a header, though maybe not one you would expect. Each email message sent has a unique message-id. When gmail sees 2 emails with the same message-id, it keeps the first (the one you sent) and discards the second (the one from the list). I wrote the list software to keep the message-id of a message sent to the list and duplicate it on the message going out. Two messages of the same message-id, even though they have different bodies and other headers, are the same message according to gmail.
All I have to do is assign a new message-id to outgoing emails and they'll show up in gmail no matter what. -- Michael Dinowitz On Wed, Apr 7, 2010 at 11:52 AM, Tom Chiverton <[email protected]> wrote: > On Wednesday 07 Apr 2010, Michael Dinowitz wrote: >> If there is a call for it, I can alter the list code to 'force' gmail >> to always display an email that you send to the list, resulting in one > > Is this just a header or something other software can use ? > > -- > Helping to proactively transition fourth-generation meta-services as part of > the IT team of the year 2010, '09 and '08 > > **************************************************** > > This email is sent for and on behalf of Halliwells LLP. > > Halliwells LLP is a limited liability partnership registered in England and > Wales under registered number OC307980 whose registered office address is at > Halliwells LLP, 3 Hardman Square, Spinningfields, Manchester, M3 3EB.
