UNIX for Dummies Questions & Answers

Long story short, I have everything working in my SOHO which would include Postfix,Dovecot(imap),Roundcube,bind and is ready to recieve email from the outside using this tutorial:

https://workaround.org/ispmail/wheezy

I also setup my internal DNS server using:

https://wiki.debian.org/Bind9

My questions are:

1 - How do I tell godaddy dns servers (mx record) to send email to my domain imap.blah.com?

2 - Is there any thing special I need to do on my end via bind9?

essentially I just need a quick how to in getting this going. So my goal that I am trying to achieve is.

1 - Allowing my employees the ability to be able to check their email from any location via roundcube. Ex. https://blah.com/roundmail

2 - If not using webmail then being able to configure a email client (thunderbird or evolution) via imap.blah.com TCP:IMAP:143/SMTP:25 to be able to recieve and send email.

All help is most appreciated.

You need to login to your domain registrar and insure the registered DNS name servers for your domain are pointing to your DNS name server.

Then you need to login to your DNS name server provider and make sure you have your correct A and MX records set up for your mail server.

You need to be aware that DNS records have TTL (Time-To-Live) configurations, so you should set this very fast (must less than one hour, maybe a just a few minutes) when experimenting with new configurations.

thanks for the reply. I forgot to add that I am also hosting our internal bind9 DNS server inside the SOHO as well. Can you clarify a little more what I need to do on the Godaddy DNS section for my domain.
