Hostname on the system is wrong--is it &quot;example.it&quot;?

You've got myorigin set in main.cf. Nobody ever sets this correctly, and you don't want it in a virtual hosting environment, anyway...so unset it.

Hi,
I have the same problem:

my hostname is &quot;www.comunicazioneitaliana.it&quot;
my main.cf does not set myorigin
anyway when I send an e-mail to a virtual server (info@duuytren.it) I have this error in the log file:

[code:1]to=&lt;info.dupuytren@www.comunicazioneitaliana.com&gt;, orig_to=&lt;info@dupuytren.it&gt;, relay=none, delay=0.09, delays=0.04/0.04/0/0.01, dsn=5.0.0, status=bounced (User unknown in virtual alias table)[/code:1]

What can I do to solve this?

Thank you

ok..
I ave resolved.

with this <a href='http://www.virtualmin.com/component/option,com_openwiki/Itemid,48/id,ema... target='_blank'>Good Guide</a>

[code:1]Usermin Webmail Sends With Incorrect From: Address

In most cases, if Usermin webmail does not include the correct From: address, it is incorrectly configured. The default was not being set correctly in our automated installer until recently due to a bug.

The old default would default to a From: address of the form &quot;user-domain@hostingco.tld&quot;, when it should instead be &quot;user@domain.tld&quot;.

To correct this problem:

Browse to Webmin:Usermin Configuration:Usermin Module Configuration:Read Mail page

Locate the option labeled From: address mapping file, and set it to /etc/postfix/virtual

Locate the option labeled Address mapping file format, and set it to Address to username (virtusertable)

Save it.
[/code:1]

Usermin Configuration..........
Usermin Module Configuration........
Read Mail..............
i ave set:

Allow editing of From: address Yes
...
From: address mapping file /etc/postfix/virtual
Address mapping file format Address to username (virtusertable)

Okay, so, your email account is &quot;prova@example.it&quot; -- but, whenever I try to send a mail to it, it seems to be trying to forward that to a different address -- &quot;prova.example@example.it&quot;.

I'm not sure if you're intentionally forwarding that or not, but my guess is that prova.example@example.it doesn't exist, or isn't setup correctly.

<div class='quote'>If i try to change /etc/postfix/virtual :</div>

I'm confused. Why are you changing the Virtualmin created entries?

If mail isn't being delivered in this case, it's because your server is misconfigured. I can think of two reasons:

Hostname on the system is wrong--is it &quot;example.it&quot;?

You've got myorigin set in main.cf. Nobody ever sets this correctly, and you don't want it in a virtual hosting environment, anyway...so unset it.

I'm betting on the latter.

Switch to the daemonized version of clamav (clamd+clamdscan). This is configurable in the Email Messages:Spam and Virus Scanning page. (The SpamAssassin service will need to be started before you switch to spamc, the daemonized version of it...but on CentOS, Virtualmin will setup and start clamd for you, if it's not already running. The spamassassin service can be started and set to start on boot in the Webmin:System:Bootup and Shutdown module.)

<div class='quote'>Can I suggest that Virtualmin makes the right configuration when joined to postfix?</div>

As long as your hostname on your system is set correctly, and matches what Postfix thinks it is (it gets it via the gethostname system call), no extra configuration is needed. Usually, after running install.sh mail works fine.

What happens if you type:

postmap /etc/postfix/virtual

And then restart Postfix:

/etc/init.d/postfix restart
