[postfix]550 ..: Recipient address rejected: User unknown in virtual mailbox table

I've been trying for hours and hours getting my postfix to work, but it just won't work.

Of the three scenario's, i can't get one to work:
- external mailserver (isp) to local mailserver (mine) WORKS
- local mailserver (mine) to local mailserver (mine) WORKS
- local mailserver (mine to external mailserver (isp) PROBLEM!

I get this error:

Code:

.. postfix/smtpd[16293]: NOQUEUE: reject: RCPT from *host*[*ip*]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<dev>

It just doesn't seem to get that external.isp isn't my server, but it has to go external . The external.isp could be anything from hotmail, gmail to some little mailprovider.

My configs for as far as they'll be needed, i added to the bottom.


Hopefully someone can help me getting this up, becuase i've been spending much more hours than I would. Thanks in advance!!

Please check if your server is blacklisted: http://mxtoolbox.com/blacklists.aspx

 

All okay. Except for some timeouts, but that won't be the problem i guess:

 

I see that mydestination is empty in your main.cf. That could be the problem. Please change it and restart Postfix.

 

What should I change it to? I'm using multiple domain names, which are saved in a mysql database table (used to virtual_mailbox_domain).

Do I have to use a single domain for my host? Or use a SQL statement? It hasn't been empty all the time, i've tried different things. But in working configs I found it was mostly empty.

Please suggest what I could put in there (for example).

 

You must use a different hostname from what you've stored in the MySQL DB. What's the output of

Code:

hostname -f

? Is this hostname stored in the MySQL DB?

 

This outputs dewildevds2.jronline.nl which is not hosted as a maildomain. But I'm connecting to the mailserver through the hosted domains itself. For example:

Works for incoming at least. Outgoing can connect, but not sending as mentioned. Previous settings I've tried are:

None of them did work. Neither did this change (dewil...) Thanks for helping this far anyway..

 

Are the host and IP address your own ones or the ones of the remote host?

 

My client IP running the mailclient.

 

Huh? So you're running a mail server on the client?

 

No, I'm running it on the external server. Is there any documentation about where this message come from? It checks my outgoing recipents on the local MySQL table, but it should just send it away (as that is why it's there :S). Hope it's possible to solve.

 

I'm not sure what the problem is, but you should compare all your configuration files with the ones from the tutorial again to rule out typos, etc.

 

I didn't do a tutorial, just installed it by 'yum' and configured it by hand.

Looks like it's looking in the table for incoming e-mail, when sending e-mail. What settings could influence this? Is there any way that auth could fail and cause this problem?

 

What's in /etc/postfix/mysql_mailbox_domains.cf and
/etc/postfix/mysql_mailbox_maps.cf?

 

mysql_mailbox_domains.cf:

users contains a column called domain which holds the domain.tld for the email.

mysql_mailbox_maps.cf

Correct path (when prepending the base path)

 

Anyone who has an asnwer?

 

I think i've found a part of the problem. The outgoing port is 587 (submission) and I think that has to be routed somewhere to port 25? But it isn't anywhere? Shouldn't it be in master.cf?

 

What's the output of

Code:

netstat -tap

?

 

Here's the output:

 

Looks ok. I don't think that port 587 is a problem for outgoing emails...
