Hello,
I have a problem with postfix when i try to send emails from usermin or email clients. Before i change my hostname, all worked like a charm, and now (also after create sub-server), smtp is not working.
Can you help me to correct this problem ?
i have put some information about my configuration >(mydomain) = my domain name... In virtual domains, the map specification seems to be ok > hash:/etc/aliases
The error message in mail log > Recipient address rejected: User unknown in virtual alias table; from=<test@(mydomain).com> to=<test@(externaldomain).com> proto=ESMTP helo=<[192.168.0.4]>

Thank you
Howdy,
If you changed the hostname, what you'll want to do is make sure there's matching entries in your /etc/hosts file and on the mydestination line of your /etc/postfix/main.cf.
There needs to be a line in your hosts file and on your mydestination line that exactly matches your servers hostname.
If you make changes to your main.cf file, make sure you restart Postfix afterwards.
Let us know if that does the trick!

Hi Eric,
The matching entries are ok :
/etc/hosts
178.32.5.242 server.(mydomain).com server
/etc/postfix/main.cf
mydestination = $myhostname, localhost.$mydomain, localhost, server.(mydomain).com
I have restarted postfix, but the problem persist
Thank you so much for your help

Hrm, in the logs above, I see a reference to the address 192.168.0.4. If your server is behind a NAT firewall, I believe you'll want to use that 192 address in the hosts file, rather than the external IP address.
Also, just to be super-sure, if you run the command "hostname" on your server, do you see the correct "server.mydomain.com" returned?

i Eric,
I'm really glad to have your help...
The reference 192.168.0.4 is about my computer from what i have sent the email test (with OSX "MAIL" client). The server is on OVH. I have installed CSF (stoping the service doesn't resolve the issue).
About Hostname 100% sure :
It is the same as the postconf... mydestination = $myhostname, localhost.$mydomain, localhost, server.(mydomain).com
In > cat /etc/postfix/virtual for the test email i have : test@(mydomain).com test.(mydomain)
The strange thing is that it worked before... Other thing is about the recipient... if i try to send to google user, no problem.. but i think it's about "MAIL" client and automated relay... relay=gmail-smtp-in.l.google.com
Thanks again for your help

Eric,
I have to thank you for your efforts, now the problem is resolved.
I have just found that the problem was double : - for usermin, i thonk that i haven't test after change postfix conf. - for email client, the problem was that i have put smtp.mydomain.com instead of mydomain.com !!
Thanks again,
Angang
