SMTP Set up

SMTP Set up

Hey,

We're migrating over from Zoho mail to Zeptomail and I'm having difficulty setting up the account.
Our previous SMTP Settings:
SERVER: smtp.zoho.eu
PORT: 587
EMAIL: [our email]
PASSWORD: [our password]

I'm changing them to the following for Zeptomail setup:
SERVER: smtp.zeptomail.eu
PORT: 587
EMAIL: [our email]
PASSWORD: [our password]


But I'm sending test e-mails and receiving anything. What am I doing wrong?
