Do i need those @ signs in the (A) record section of the dns? it says warning. I was under the impression that putting that in enables someone to get ot the site with just http://example.com to get to the site. vs www.example.com needs a www (A) record.

[falko]

What's in /etc/resolv.conf and your named.conf?

[chachdog]

i just started deleting dns records. i guess it didn't like the way i put in an MX record. can you not put in a mx record to have it point to a different server?

[till]

You can put in a mx record to any server you like, so this can not be the probelm.

But MX records never contain a @ sign. What exactly did you enter as mx record?

[chachdog]

mail.example.com

without a period at the end. I found that a period at the end breaks Bind

what is the difference between an mx record and an (A) record pointing to mail.example.com

whenever i put something in mx it breaks bind.

i tried mail as the hostname and example.com as the mailserver.

Do i leave hostname blank?

I have the mail server in there as mail.example.com and bind didn't go offline.

[chachdog]

how can i troubleshoot mail sending but not recieving? i can send from myself within webmail to myself and see that mail but outside mail is not getting in. smtp and pop are set to allow on the firewall.

thanks

Please have a look at your mail logfile for errors.

Never add a period in ISPConfig at the end of a domain name, ISPConfig adds the dot at the end automatically if nescessary. Leave the hostname blank.

[chachdog]

Please have a look at your mail logfile for errors.

where is this log you speake of? I want to check it out and maybe post it up.

[falko]

It's in the /var/log/ directory.

[chachdog]

I am new to linux. I am getting it slowly but key word is slowly. thanks for being patient with me. :)

Did you have a look at your mail log if there are errors in there?

I see you use Sendmail. Sendmail's a nightmare to configure. I recommend to use Postfix instead. Which distribution do you use?

[chachdog]

how can i tell which one is loaded? i see postfix and sendmail under ispmanagement\server\settings\email for services. can i just pick postfix from the drop down menu?

how can i see if it is loaded/running?

thanks.

Ok, what's in /etc/redhat-release? I tend to think that it's a CentOS or RedHat system.
