I looked on the forums and couldn't find an answer to this, so I hope you can help me.

I have 4 separate domains that I have added to Zoho mail so I can deal with all of them in one place. I am able to recieve emails from all four domains, but I am not able to send emails from Zoho for three of these domains, only my original email that I established the service with. 

I've installed the three domains via the pop3 process outlined.  Can someone please take a look at my account and point me in the right direction?

Many thanks,

Elaine
