Domain Management Help for Mail Server

[blend525]

I am trying to set up a E-Mail Server and are running into a bit of a problem with : A, Cnames, MX settings.

Unfourtunatly stupid godaddy will offer no help whatsoever :(
Are getting all kinds of errors trying to send/recieve mail.

frostcity.com is the domain name
173.8.45.243 is the static public ip that is connected to my mail server
Could somebody please take a look at the settings i have and tell me what i need to have where?

I took a pic of the settings page, its here:

www.dreadfulzombie.com

Also how would you get the secure mail services to work? such as SMTPS- 465
POP3S- 995

Looking at the settings you have I believe I see the problem. I also have godaddy and it can be confusing as to what you should put where. You need to point mail.frostcity.com to frostcity.com instead of smtp.frostcity and pop.frostcity.com or change the entries for smtp and pop to point to frostcity.com. If you look at the settings you have the only location you point to the IP address is the frostcity.com one.
I when to get a snapshot for my server from godaddy and can't get to the totalDNS server right now they are doing maintenence...

Total DNS: (Available)
ARecord * 66.100.167.20
ARecord txlinux.com 66.100.167.20
CNAME mail.txlinux.com txlinux.com
CNAME email txlinux.com
CNAME pop txlinux.com
MX @ txlinux.com

>>rch1231:
While your example is technically correct I would not recommend it.

DNS entries for mail records ( MX ) are structured: @ IN MX <PRIORITY> <HOST>

Where: @ : defining entry. @ Defaults bind to the zone Priority : A numeric priority. The lowest-numeric is served first. If it cannot be contacted it starts climbing up the priority. 0-first, 1-second, 2-third, etc. Host : DNS hostname to deliver email to.

Now the ultimate gotcha:
The HOST for an MX record MUST be an A and not a CNAME record. Some SMTP servers will send emails to a CNAME , and others will not. So if you have this configuration you will only have problems receiving email from *some* people, making the problem all that more confusing.

So in rch's example the MX is pointed to txlinux.com, which is an A record so all is well. However in the future if that was changed to "mail.txlinux.com" it would break, even though mail is a CNAME for @.>>blend525:
- Delete "smtp" and "mail" from MX .
- Delete "smtp" and "mail" from CNAME .
- Add "mail" to A .
- Add MX for priority 0, mail.domain.com (where mail is the recently created A record).

[blend525]

this stuff is crazy :)

A host: mail Points to: 173.8.45.243
MX Host: @ Goes to: mail.frostcity.com Priority: 10
MX Host: @ Goes to: smtp.frostcity.com Priority: 0

Under CNAMES, the Host 'mail' was deleted
there is no 'mail' CNAME, only a 'mail' Host for A

if i delete smtp and mail from 'MX' then i will have no mx records.

you said"The HOST for an MX record MUST be an A and not a CNAME record"

the '@' symbol for MX Hosts should be changed to 'mail' ? or does that '@' symbol point to A Host by default?

all i know is it works now with gmail and hushmail send/recieve
in my email client(thunderbird) i have to set both pop3 and smtp settings to: mail.frostcity.com, that seems kinda odd seeing how smtp,
i thought should be smtp.frostcity.com

Hello,

I hope this helps I finally managed to get into Total DNS manger and did an export of the zone file for my server:

; NS Records
@ 3600 IN NS ns25.domaincontrol.com
@ 3600 IN NS ns26.domaincontrol.com

; A Records
* 3600 IN A 66.100.167.20
txlinux.com 3600 IN A 66.100.167.20

; CNAME Records
mail.txlinux.com 3600 IN CNAME txlinux.com
email 3600 IN CNAME txlinux.com
pop 3600 IN CNAME txlinux.com
smtp 3600 IN CNAME txlinux.com
my.txlinux.com 3600 IN CNAME txlinux.com
www 3600 IN CNAME @
imap 3600 IN CNAME imap.secureserver.net
ftp 3600 IN CNAME @
webmail 3600 IN CNAME webmail.secureserver.net
e 3600 IN CNAME email.secureserver.net

; MX Records
@ 3600 IN MX 10 txlinux.com

; TXT Records
@ 3600 IN TXT "v=spf1 a mx ptr ~all"

If you are going to be using the system for a mail server then you need to make sure you add the TXT entry and also contact the company you got the IP address from and make sure that they set up a rDNS (reverse DNS entry) for your domain. Many mail servers (including mine) will not accept mail from an email server that does not have a matching rDNS entry.

To check that the settings are correct use nslookup from either a windows command prompt or linux shell prompt. nslookup will return your IP if DNS is set up correct. Then nslookup will return your domain name if rDNS is set up correct.

Check DNS:
[root@srvr3 ~]# nslookup txlinux.com
Server: 209.18.47.61
Address: 209.18.47.61#53

Non-authoritative answer:
Name: txlinux.com
Address: 66.100.167.20

Check rDNS:
[root@srvr3 ~]# nslookup 66.100.167.20
Server: 209.18.47.61
Address: 209.18.47.61#53

Non-authoritative answer:
20.167.100.66.in-addr.arpa name = txlinux.com.

>>blend525:

So is it working now or are you still having issues? I would delete "smtp." altogether. Not many people use that. Just point everything at "mail." like you're doing now.

[blend525]

yea its workin like it is, may not be perfect,afraid to change it again,
i added another domain to test different settings, but it takes forever having to wait for updates.

i do have a question about the ' TXT ' , 'add a new TXT record '

am i able to put just any text i want here? like a description of what the server is for.

Something that will show up when i look up the DNS Records for frostcity.com

on the 'SPF' wizard, i have a choice: This domain sends mail through....
A. GoDaddy.com, Inc. only
B. GoDaddy.com, Inc. and an ISP
C. an ISP or other mail provider
D. no email is sent from this domain

not sure what to choose there. A,B,C, or D?

Also, i enabled the 'SPF' spam filter and are wondering if these settings will work.
v=spf1 a mx ptr mx:mail.frostcity.com mx:smtp.frostcity.com ~all

Thanks for all the help on this.

>> i do have a question about the ' TXT ' , 'add a new TXT record '. am i able to put just any text i want here? like a description of what the server is for.

Yes, you may put any value you desire. See RFC1614 for the TXT record format.>>on the 'SPF' wizard, i have a choice: This domain sends mail through....

I would think if you picked option "C" it would let you provide other SMTP server(s), or allow you to define an SPF record.

Determine what might have caused this failure,

resolve the problem, and initiate registration of

the DNS records by the domain controller. To

determine what might have caused this failure,

run DCDiag.exe. You can find this program on the

Windows Server 2003 installation CD in

Support\Tools\support.cab. To learn more about

DCDiag.exe, see Help and Support Center. To

initiate registration of the DNS records by this

domain controller, run 'nltest.exe /dsregdns'

from the command prompt on the domain controller

or restart Net Logon service. Nltest.exe is

available in the Microsoft Windows Server

Resource Kit CD.

Or, you can manually add this record to DNS,

but it is not recommended.
