Able to send but unable to receive email from external mailserver

Hi All,

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 Master

Mail server:

example.com. Default 10 mail.example.com.

A record:

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: person1@example.com SMTP -> FROM SERVER: 250 2.1.0 Ok RCPT TO: person1@example.com SMTP -> FROM SERVER: 250 2.1.5 Ok Sending Mail Message Body... SMTP -> FROM SERVER: 354 End data with . SMTP -> FROM SERVER: 250 2.0.0 Ok: queued as AB5571382C5 Message completed successfully.

But http://www.intodns.com/example.com came up with following errors,

1. 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!

2. 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.

3. ERROR: looks like you have lame nameservers. The following nameservers are lame:

4. 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.

5. No valid SOA record came back!

Kindly advice. Thanks in advance.
