Emails in ISPConfig

f

I've done that. Both commands did not return anything. So present status is:

1. Can login to roundcube webmail, but inbox is empty.
2. Mails appear to send, and are listed in sent items folder, but do not arrive.
3. Admin mails from the ISPConfig dashboard appear to get sent but do not arrive.
4. Cannot setup a remote client account in Outlook due to "Send test email message: The server responded: 451 4.3.0..."

There are quite a lot of files in the postfix folder but not sure where to start looking if postfix is causing the issue.
Thank you for your help so far, I feel like we are making progress.

 

Here is the mail log

Reset the message max size from 0 to 900000000. Still this in the log

And you have a content_filter in the main.cf?

 

content_filter = amavis:[127.0.0.1]:10024
Is this a port filter too?

Might this be a firewall issue?

 

Should I try reinstalling some programs?

 

Blocked MTA-BLOCKED {TempFailedOpenRelay} = postfix does not accept mails (on port 10025).

 

That's understandable. I have no idea why or how mail would be coming in on port 10025 anyway? It isn't something I set up although I can see it in the master.cf file. I assume I should change this line..

Code:

127.0.0.1:10025 inet n - - - - smtpd

EDIT: I've uninstalled postfix and will reinstall.

 

This should not change your configs... i use the setups from howtoforge quiten often and never had such a problem.

 

The postfix master.cf has this entry

Code:

smtp  inet  n - n - - smtp

The 2nd n being chroot. Is this correct?

 

I found a part I may have not done, in the hosts file

Please explain the middle line more clearly, or whether it is unlikely that this omission is causing the 451 4.3.0 error message.
