SMTP Error 451

I have just updated my servers to v3.2.3 and the email has stopped working with an error

SMTP Error (451): Failed to add recipient "[email protected]" (4.3.5 <localhost[:::1] Client host rejected: Server configuration error)

When I was upgrading I stuck to the default settings and passwords I had previously used when first installed

the webserver is working fine so I can log in to the RoundCube web email but I am not receiving and not able to send an email.

From what I have read this is a local issue but cant see why its an error at all

 

Hi there

Thank you for the reply

Yes, I can confirm the email was working before the update.

I can confirm that

Code:

$config['smtp_server'] = 'localhost';
$config['smtp_port'] = 25;

I can confirm that the update script reconfigured my services as per default settings I have also ran it with the --force switch

There are no custom config templates in:

Code:

/usr/local/ispconfig/server/conf-custom

I have also confirmed that email is not being sent from the account I logged into the account with i.e. local mailsystem

edit:
So error in the mail.log file

 

I've just checked in the mail.err log and 3 entries

Code:

Mar 22 12:10:40 martin amavis[23894]: (23894-07) (!!)AV: ALL VIRUS SCANNERS FAILED
Mar 22 15:54:14 martin dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF
Mar 22 15:54:14 martin dovecot: auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused

I'm guessing this is not good?

 

I've looked but the results are not making much sense to me.

 

All my emails have stopped con anyone point me to a solution please?

 

Thanks Till

But have already tried that with no success
I am logged in as root as that is how I have always had my servers configured

 

So how come it stopped after I ran the ISPC3 update?

in the /etc/postfix/mysql-virtual_transports.cf

the host is set to

Code:

hosts = 2.0.0.1

is this correct surly it should be 127.0.0.1 for local host

 

Yes it was but that is not the problem

Thank you

 

Outstanding Till,
I would never have thought such a simple error would course that problem.

The error was when I updated my hosts file to accommodate my nameservers.
And obviously, this error never showed up until I updated/upgraded ISPconfig

Many thanks again...
