This "thread id" in the subject line only works if you send out individual emails. This is not going to work for most boards.

A lot of egroups sites that i am intersted in have traffic of about 75 - 200 posts per day. Some of the lesser ones more around 25. No one wants 200 posts per day in their email box. They want maybe 4 emails with 25 posts.

Lots of these users are used to just hitting reply and sending a message, as there is no threaded strucuture they just make the title up as they go along.

If we do this batch mailing of say 25 emails (i think essential) then this is something that will have to change to keep the email structure. Personally i would want each post to have an email link by it as i think chris suggested with say popaccount34343@domain.com (with 34343 being the thread id). The subject title would then be the subject title of a post like you can do on the forum.

For new threads they would have to write the exact words new thead - Title in the subject line. This is to prevent getting hundreds of new threads from people just hitting reply. Either that or a new thread has to be sent to a different email box.

This is why 1 pop3 account will not work, need to be able to accept lots of different incoming email address, 1 for each thread.

Interested to here what john (via james ) thinks would be a good way to do this and what he actually thinks of the idea in the first place.
