554 5.7.1 <test@myotherdomain.com>: Relay access denied

[mramin05]

hi guys,
I have installed postfix and dovcot as the tutorial "The Perfect Server" in CentOS 5.2.
I can access to that remote server by ssh secure shell.
after completion I want to test my postfix.
This is my steps:



$>elnet mail.mydomain.com 25
Trying 222.99.123.211...
Connected to mail.mydomain.com.
Escape character is '^]'.
220 mail.mydomain.com ESMTP Postfix
mail from: testuser@mydomain.com
250 2.1.0 Ok
rcpt to: mramin05@yahoo.com
554 5.7.1 <mramin05@yahoo.com>: Relay access denied

If I use localhost instead of the mail.mydomain.com
then no problem at all.

# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mail.mydomain.com ESMTP Postfix
mail from: test@mydomain.com
250 2.1.0 Ok
rcpt to: mramin05@yahoo.com
250 2.1.5 Ok
data
354 End data with <CR><LF>.<CR><LF>
.
250 2.0.0 Ok: queued as 0D504203C1
quit
221 2.0.0 Bye

hey dude,
I am not too good at it but i think your problem is at mydestination variable in main.cf

your relay access is denied because i guess at mydestination in main.cf you dont have mail.mydomain.com you have only localhost that's why u connect with localhost.

Add after localhost, mail.mydomain.com and u should be good. Cheers

hi mirostz,
Thx for your reply.

Add after localhost, mail.mydomain.com and u should be good. Cheers

I have solved the relay problem by this way a hour earlier. Now my problem is
When I want to mail from local PC by ruby using my smtp server( remote) it create error. I am using user Authentication(login).here is setting

ActionMailer::Base.smtp_settings = {
:address => "mail.mydomain.com",
:port => 25,
:domain => "mydomain.com",
:user_name => "test",
:password => "xxxxxx",
:authentication => :login
}

But If it send mail from the server computer then it ok.
Is there any config problem?
Please help me.Thx in advance.

hey dude,
Well i dont use ruby but try squirrelmail it is easy to install and it is with web interface very good mail program. you have already dovecot and postfix running so just install sqruirrelmail and have fun

The problem is that you must authenticate if you're not sending from localhost.
