Relay access denied

Hi Guys,

Please can i ask why i cant sent email from a email account or all email accounts i have setup for my domain...

here have a look...

Quote:

could not be delivered to some or all of the intended recipients.

User<xxx> - (554 <xxx>: Relay access denied)
User<xxx> - (554 <xxx>: Relay access denied)

here i did this as well

Quote:

FAIL Acceptance of postmaster address ERROR: One or more of your mailservers does not accept mail to xxx. Mailservers are required (RFC822 6.3, RFC1123 5.2.7, and RFC2821 4.5.1) to accept mail to postmaster.

xxx postmaster response:
>>> RCPT TO:<xxx>
<<< 554 <xxx>: Relay access denied

and this

Quote:

PASS Open relay test OK: All of your mailservers appear to be closed to relaying. This is not a thorough check, you can get a thorough one here.

xxx OK: 554 <Not.abuse.see.www.DNSreport.com.from.IP.203.56.12 7.1@DNSreport.com>: Relay access denied

any suggestion would be aprechiated...

relay rules is the answer

brainz,

I suppose you have Postfix as your mail server, (in any case you should when asking this kind of questions give more info, like OS, mailserver, versions)

but the important thing is that your have i quote:
PASS Open relay test OK: All of your mailservers appear to be closed to relaying

relay is the property of a mail server to restrict who (ip, user, Mailclient) can receive and send mails (not the best definition but sufficient), so in the postfix main configuration : main.conf you can enable or disable this restricctions. There are a set of rules, open them and try them each one, so go search google.

be careful becouse if you open all the restricctions you can be matricaulated as an open relay server and others servers may not receive mail that your server sends.

I think the success of a mail server is a good set of relay rules and a good set of antispam procedures. (sometimes relays rules prevent spamming ) ;) ;)

hope this helps, anf good luck

Hi Guys,

I also did this

Quote:

telnet localhost 25
ehlo localhost

and got this...

Quote:

ehlo localhost
250-xxx
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250 8BITMIME

which i think look right...

any advice would be apreciated....

ohhh just remebered as well this issue first started when i tried to login to squirrelmail for the account and it would not recognise the password... i changed the mailboxes password and it still does not let me in....

Just wondering if this could also be related to the issue in anyway...

Quote:

Please modify /etc/hosts so that it looks like this:

Code:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

Restart Postfix afterwards.
