Hi All on a fresh install i am seeing errors on rsyslog status (action 'action-5-builtinmfile' suspended (module 'builtinmfile')........) also no log files is being created. the rest seem to work.
hi Till I restarted and the rsyslog seems resolved, but now I get this error when sending mail, "Sender address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command)"The server is on, Ive checked DNS its correct, seems to be problem on the server with postfix Server: ms3.serverflex.co.za (Ubuntu 24.04.2 LTS (Noble Numbat)) ISPConfig 3.2.12p1
There is no email error.log anymore today, you should find everything in mail.log file on Ubuntu. Which tutorial did you use to install the system?
Perfect Server Automated ISPConfig 3 Installation on Debian 11 and Debian 12, Ubuntu 22.04 and Ubuntu 24.04 I used this: wget -O - https://get.ispconfig.org | sh -s -- --use-ftp-ports=40110-40210 --unattended-upgrades --interactive --monit [email protected]
I get a lot of these in the log postfix/smtpd[2065]: disconnect from localhost.localdomain[127.0.0.1] ehlo=1 quit=1 commands=2 2025-04-02T07:06:56.397231+00:00 ms3 dovecot: imap-login: Disconnected: Aborted login by logging out (no auth attempts in 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, secured, session=<x7J2TMYxTKl/AAAB>

The log indiactes you have an issue with email receiving. According to the log, you have not created a mailbox for the email address [email protected] on the new ISPConfig server yet.
That's not the reason for the issue. The problem is that you do not seem to have created the recipient mailbox on the new server yet.
Just a guess, the error message is from server ms1.serverflex.co.za and it reports that it does not has the sender address in its virtual mailbox table. maybe you create the sender email domain on the server ms1.serverflex.co.za as well.
Then the mail server is working fine but you might have create email domains or mailboxes for the same domain on another system.
You should tey to sort out which address is where and douböe-check DNS. The new server is working fine, you just seem to have an issue that the servers where you created mailboxes and the DNS which says where mailboxes and domains shall be is not fully in sync yet.
