I've found this morning that a special not negotiable email format might cause the Universal Thread listserver to retry indefinitely to send this message.

That is explaining why the Universal Thread listserv members didn't receive any message during the last 8 hours.

I've put additional code to take care of that and this is now fix. When the listserver detect that an email is not negotiable, the member will be remove from the listserv and will receive a notification when entering the Universal Thread.

You should have received all those waiting messages now. In the last 10 minutes, the listserv processed 25 messages and distributed 2500 emails.

Thanks.
