Cannot Send Emails from iPhone

Cannot Send Emails from iPhone

Hi All,

I'm trying to add my Zoho account to my iPhone mail. The Zoho app doesn't allow the keyboard to turn horizontally and it's driving me up the wall. 

I was able to add the account successfully and all my emails synced, but for some reason when i try to send an email I get an error saying "A copy has been placed in your Outbox. sending the message content to the server failed."

I have verified that my password and username are typed correctly, that the SSL is on and that the port is correct. What am I doing wrong?!

One odd thing that I noticed was that in the incoming settings, my original login email (Hotmail address I used to create the account) and password work but in the outgoing settings my alias email and password worked. I've tried switching them around, but when I switch the incoming info the emails don't sync anymore and when I change the outgoing info it ways wrong user info. 

Any insight would be much appreciated.

Thanks so much!!!!
