The domain rodney.rhwebhosting.com seems not to exits in DNS. Please create a DNS-A Record for rodney.rhwebhosting.com in the authoritive DNS server for rhwebhosting.com that points to your server IP.

Till do i have to do that for all email addresses, the rodney.rhwebhosting.com is rodney@rhwebhosting.com, but it does not accept it with the @ when i try it in telnet?

This has nothing to do with mail users. You are trying to send mail to the hostname rodney.rhwebhosting.com and this hostanme does not exist in DNS. So you will have to createit if you want to use it.

that went through but i still cant send mail from mail clients, im totally baffled.

Ok, please try to send a mail from a mail client and then post the exact error message that appeared in the mail log. It might be a misconfiguration in the mail client.

28th July 2008, 16:13
Till nothing appears in the mail log.

28th July 2008, 16:19
Ok, then you are not connecting to your server.

Please make sure that you set the smtp and pop3 server in your mail client to:


or the IP address of your server.

28th July 2008, 17:26
Till i have set it, it recieves email fine, just doesnt authenticate on sending

28th July 2008, 17:31
If no line appears in the mail log, the your mail client dioes not connect to the right server. Please edit the smtp settings of your mail client and set it to rhwebhosting.com or the IP address of your server.

28th July 2008, 18:53
till i have double checked, i have tried it with mail.rhwebhosting.com rhwebhosting.com and the IP address. Each time it says host not found

28th July 2008, 19:01
Ok, then please check the firewall on your server, on your client and if both are open for smtp connections, then ask your provider if they block smtp traffic.

One side note, make sure that you did not enable ssl, tls or any similar setting in your mail client.

28th July 2008, 22:20
my provider doesnt block it, the server is in a datacenter, no firewall and i checked the tls ssl etc connections arghhh im pulling my hair out lol all for one stupid client lol

I tried some things for you:
telnet rodney.rhwebhosting.com 110
failed -> no dns record

telnet mail.rhwebhosting.com 110
user: rodney@rhwebhosting.com

if you can login there and the pass is accepted and you can see the mail with list then it is ok

open ports:
Interesting ports on www.rhwebhosting.com (

can you connect with a webmailclient ?

is what i can find in the logs, i was trying it with different settings none worked :)

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'jinx11239@aol.com'. Subject 'test', Account: 'mail.rhwebhosting.com', Server: 'mail.rhwebhosting.com', Protocol: SMTP, Server Response: '554 5.7.1 <jinx11239@aol.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79

more errors and i have SSL turned off so i am miffed

Jul 28 20:07:02 server2 postfix/smtpd[10651]: warning: ool-18beb074.dyn.optonline.net[]: SASL LOGIN authentication failed: generic failurePlease try this:
adduser postfix sasl
and restart Postfix and saslauthd.

29th July 2008, 21:08
no that still gives me the same error

30th July 2008, 08:37
But the sending for other accounts works with external clients?

If not, please compare the sasl and postfix configuration of your setup with the one found in the perfect setup guide for your linux distribution. Especially make sure that there are no whitw spaces at the end of the config lines.

Thanks Till, but its every account on that server, so in the end im transplanting them to a new server.
