Outgoing emails have stopped sending in Newton

Outgoing emails have stopped sending in Newton

I'm using Newton Mail App ( http://newtonhq.com) with Zoho IMAP and everything was working fine until Wed April 26 when my outgoing emails just stopped and are now stuck in my outbox in the Newton app.

Receiving emails works fine.

Please help. This is urgent.

I am currently writing handwritten letters and folding them into envelopes and sending out via snail mail to my 8.5K customers around the world and my hand is tired :)
