I am a novice in networking and recently I have started to do this webmastering stuff out of my interest.
I have configured my users and email in the Virtualmin/Webmin interface. I have got no problem in sending email to external mailserverz (Gmail, Hotmail, Yahoo) but couldn't receive emails.
I have also done the zone configuration in Bind DNS section by looking at one of the documentation online.
Please find my zone records below,
example.com. Default 10 mail.example.com.
example.com. Default xx.xxx.xxx.xx
mail.example.com. Default xx.xxx.xxx.xx
ftp.example.com. Default xx.xxx.xxx.xx
ns1.example.com. Default xx.xxx.xxx.xx
ns2.example.com. Default xx.xxx.xxx.xx
www.example.com. Default xx.xxx.xxx.xx
Name server record:
example.com. Default example.com.
example.com. Default ns1.example.com.
example.com. Default ns2.example.com.
The following command results is,
host -t MX example.com
example.com mail is handled by 10 mail.example.com.
My SMTP test in wormly results in the following output,
Connecting... SMTP -> FROM SERVER: 220 example.com ESMTP Postfix SMTP -> FROM SERVER: 250-example.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN MAIL FROM: email@example.com SMTP -> FROM SERVER: 250 2.1.0 Ok RCPT TO: firstname.lastname@example.org SMTP -> FROM SERVER: 250 2.1.5 Ok Sending Mail Message Body...

But http://www.intodns.com/example.com came up with following errors,
Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers!
ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.
ERROR: looks like you have lame nameservers. The following nameservers are lame:
You should already know that your NS records at your nameservers are missing, so here it is again: ns1-cloud.eleven2.com. ns2-cloud.eleven2.com.
No valid SOA record came back!
Kindly advice. Thanks in advance.
