Relay Access Dinied In Postfix

[tductho]

I setup a mail server according to falko's tutorial "Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Lenny)". I send mail test in local and by webmail then Ok But when send mail by outlook express over Internet to other domains then errors "The message could not be sent because one of the recipients was rejected by the server. The rejected xxxx, Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79"

Please help me fix this problem !
thanks

You should enable SMTP authentication. Check 'My outgoing server requires authentication' in outlook / outlook express.

Hope this works.

I've checked and enable " smtpd_tls_auth_only = yes"
But when send errors

[dipeshmehta]

you need to configure it into your outlook. Under Account Properties > Server, there is Outgoingmail Mail Server > [ ] My server requires authentication. You need to check (tick) this box.

I've tick But errors

[falko]

What's the exact error message you're getting now? Are there any errors in your mail log?

[tductho]

Hi Falko
this is error in my log file when send from outlook express.

mail postfix/smtpd[20278]: NOQUEUE: reject: RCPT from unknown[IP]: 554 5.7.1 <test@yahoo.com>: Relay access denied; from=<test@company.com> to=<test@yahoo.com> proto=SMTP helo=<test>

please post your /etc/postfix/main.cf here

smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination


this statement should go into one line, if there is CR please remove it.


proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domai$


this line misses some parameters, check and compare with the howto which you followed.

if you make any changes to postfix configuration files, do not forget to restart postfix using
/etc/init.d/postfix restart

thanks Dipesh
I fix acording to how to but still errors ' relay access denied"
please note : If I add "mynetwork= my subnet" then I send local and internet ok But when go home will not use mail client as outlook or express to send mail over postfix .

[dipeshmehta]

No need to add "mynetwork= my subnet", leave it as it was. Instead put mydestination = my.company.com, company.com, localhost.company.com, localhost, localhost.localdomain

Ideally mydestination should contain all domains that you want to accept emails for.

Dipesh

[tductho]

I done as your guide But errors "relay access denied "

[dipeshmehta]

I am sorry friend, I do not have any further idea. Falko may help you.
