Business Email FAQ:


1. Business Email activation:

Please "Submit a Ticket" from NiceNIC's homepage to confirm your business Email order, then our IDC team will prepare the Email accounts as per your requirements and if your domain name is with our registrar, we will help you create the DNS records to save your time. Then we will send you the following information by replying your ticket:


Webmail URL: https://c3.icoremail.net

Admin account: admin@**********

Admin password: **********


If your domain name is not with our registrar, and/or we are not your nameserver provider, please create the following DNS records yourself:

Point the CNAME records of mail, imap, pop3, and smtp to: c3.icoremail.net

Set the MX record of your domain name to mx.c3.icoremail.net. Priority 5

Set the MX record of your domain name to mx2.c3.icoremail.net. Priority 10

Point the TXT record of your domain name to: v=spf1 include:spf.icoremail.net -all"

lease contact us by "Submit a Ticket" from NiceNIC's homepage, then we will check your MX records. If we can't locate the reason, we will request you to provide us with a test Email account so that we can further make investigation and testing.
