postfix : User unknown in virtual alias table

I am trying to configure postfix to work but i got always the same error. I can send email but i cannot get a reply.

postfix/error[26116]: 4A52811A1132: to=<prova.example@example.it>, orig_to=<prova@example.it>, relay=none, delay=0.34, delays=0.32/0.01/0/0.01, dsn=5.0.0, status=bounced (User unknown in virtual alias table)

I have checked around reading all discussion on it, but i got no solution. Any idea ? Thank you

Are you able to log into Usermin as this user?

Also, if you go into Virtualmin, choose the domain from the drop-down, and select Edit Mail and FTP users, click the email account, and then choose Email Settings.

Is &quot;Primary email address enabled&quot; set to &quot;Yes&quot;?

Alright, do you think you could email me the following details (from your Usermin account) -- you can send it to eric@virtualmin.com :

* Your username and email address

* You posted a line from your maillog above -- could you include several lines in the email to me -- all the ones relating to you receiving the message would be great.

We'll see if we can figure things out after seeing the details in your email. Thanks,
-Eric

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.
</div>

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)

Thank you again

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.

I have created the user prova in example.it domain using the function in Virtualmin -&gt; Edit Mail and FTP Users -&gt; Add a user to this server.
I have not modified it by myself.

If i try to change /etc/postfix/virtual :
prova@example.it prova.example@example.it
into
prova@example.it prova

I get always the same error.
The user prova exist into /home/example/homes/ directory

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.

I don't know whether or not this will help you, but I've encountered this error message many time. It always seems to be something in user alias. Where usrername@domain.tdl is the email address and username.domain@domain.tdl is addedd to the &quot;Additional Email&quot; options under the user account.

You right it was a configuration error. Now it work great, thank you very much..

Thank you very much !

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.)

Can I suggest that Virtualmin makes the right configuration when joined to postfix?

But... great job boys, Virtualmin is really a great job.

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.

Hi,
I also have a problem with one virtual domain,
'maryleishmanfoundation.com'

I get the error
<div class='quote'>Requested action not taken: mailbox unavailable
550 5.1.1 &lt;brian@maryleishmanfoundation.com&gt;: Recipient address rejected: User unknown in virtual alias table</div>

my server name (and hostname) is : fife.biz.

I have another domain 'parstrust.co.uk' that I can send and receive email.
I thought it was a DNS problem, but as far as I can ss its OK.

I do get this error:
<div class='quote'>Apr 27 18:31:49 srv126 postfix/trivial-rewrite[8573]: warning: database /etc/postfix/virtual.db is older than source file /etc/postfix/virtual

'maryleishmanfoundation' website was probably the first website on the new server, perhaps I did some change after that.
I think the problem is 'fife.biz' is my main server name

What happens if you type:

And then restart Postfix:

thunderbird sent email but mail server bounced it back

his message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

Neither. It's a Postfix problem.

Also, this is a completely different problem than this thread was started to address. Starting a new one for your particular problem would make it easier for us to know what's going on (I just tried going back to the start of the thread so I could figure out what's happening, and found I was reading about completely different issues from completely different users).

I have also just realised that if I login under 'Usermin' and send an email the sender is brian.maryleishmanfoundation@fife.biz
instead of brian.maryleishmanfoundation@maryleishmanfoundation.com

so I know its a virtual name problem.

thanks for any help
