I've just upgraded my Zoho account today and I'm unable to use Zoho to send mail from my website.
I'm using my php script via my website to send mail and Postfix on my VPS server (That's attempting to send via Zoho) (I've several domains on my server and I've configured some of them with Zoho) to send mail via Zoho's SMTP settings.
Receiving this error:
lost connection with smtp.zoho.com [Then my IP]
while receiving the initial server greeting.
Can anyone help me?
