I occasionally send out important announcements and newsletters via the admin area to all users - almost every time I do this now the send process falls over at some point (60K users) with no possible way to resume at the failure point. This is actually a nightmare for me and I assume most big boards using the xenforo sending system have run into this. I'd like an option when sending a mass email for it to use the deferred system - I personally will send all mass emails with this option, but understand others may not want it for every mail send. It would also be good to specify how many emails to process at once, currently I believe it's 50, but the process of queuing all of this into the deferred system im sure could use a much higher number. There are some mods that allow xenforo to integrate with other mail gateways and to use other transports but xenforo itself handles the send process and this issue is ever-present regardless of mod. Please @Mike & @Kier I'm begging something be done as I've not managed to conduct a full mail send for months now. Thanks for your consideration.
