Hi,
I am trying to setup my own mail server to serve my personal email address, “me@mydomain.com”… I don’t plan on having any other email accounts on this server aside from this one.
What I did…
Install Postfix for smtp… https://help.ubuntu.com/community/Postfix Install Dovecot for IMAP… https://help.ubuntu.com/10.04/serverguide/dovecot-server.html Install Rainloop for webmail…http://rainloop.net/docs/installation/
The Zone file for my domain… mydomain.com
-----------Begin Zone File-------------- $TTL 1800 @ IN SOA NS1.DIGITALOCEAN.COM. hostmaster.mydomain.com. ( 1395759915 ; last update: 2014-03-25 15:05:15 UTC 3600 ; refresh 900 ; retry 1209600 ; expire 1800 ; ttl ) IN NS NS1.DIGITALOCEAN.COM. MX 5 mydomain.com. NS NS2.DIGITALOCEAN.COM.

The Zone File for my webmail domain…

What I can do…
I can send email with no issues through the terminal via the command,
echo “This is a test message.” | mail -s Hello mygmailadd@gmail.com
I can also send email through Heirloom mailx
I can recieve email from my root user account (I send email to me@mydomain.com, using the terminal command)
I can login and view my inbox through my webmail.
What I can’t do…
Recieve email sent from my gmail address. (no mailer:daemon error message from my gmail at the time of sending this ticket.) Send email from my webmail app (authentication failed).
Is there something wrong with my configurations?
Thanks
