So I was originally having some problems that others were experiencing with enabling on IMAP (you guys might want to look into that). Now that seems to have rectified itself and IMAP is now enabled in the account, but there is now an issue with the zoho account emails not deleting through the mail client and emails sending. All my other email accounts are working perfectly mind you.

So I'm using Airmail 2 on mac, I've setup/tested the IMAP account which receives fine, setup exactly as per the instructions in the settings panel but there are clearly issues with the syncing of this account and smtp.

Your prompt assistance would be most appreciated.
