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 "Primary email address enabled" set to "Yes"?

Thanks for reply.

I can enter Usermin and write email to other server (i have tryed gmail). When i try to reply to this user i got the error.

Yes it is the primary email, I have cheded now

Any idea ?
Thank you !

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

Thank you very much for interesting.
I have sended you the email with all information you needed.
Thank you again

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

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.
-Eric

I have created the user prova in example.it domain using the function in Virtualmin -> Edit Mail and FTP Users -> 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

If i try to change /etc/postfix/virtual :

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 "example.it"?

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 "Additional Email" options under the user account.

You right it was a configuration error. Now it work great, thank you very much..
Just a little problem with clamav it make the cpu to 100% and i have to kill it.. Just removed antivirus from email and it is perfect.

Thank you very much !
