Relay authentication - How to know the credential ?

Relay authentication - How to know the credential ?

Hello,

I am trying to setup email relay on zoho crm, howeveron the last section "Auhtentication" if i enable it, my provider is "other" (i have my own server and host), then it is asking for username and password. The fact is that i don't know what to input on these fields, and i use 4 email addresse within the organization.

Can someone help me ? 

I did research but couldn't find any answer.

Best regards,

Loïc
