    I can't send or receive an email. I have ISPConfig on Ubuntu 18.04 LTS. The dns records are all there and they are correct. I use dovecot for the POP3 server and postfix for the SMTP server. This is the email log:

    postfix/smtps/smtpd[25144]: SSL_accept error from localhost[127.0.0.1]: Connection timed out
    postfix/smtps/smtpd[25144]: lost connection after CONNECT from localhost[127.0.0.1]
    sentora postfix/smtps/smtpd[25144]: disconnect from localhost[127.0.0.1] commands=0/0

    Nothing, it still doesn't work. It doesn't even send emails locally. This is the log:

    Jul 2 17:34:38 sentora postfix/smtps/smtpd[28425]: SSL_accept error from localhost[127.0.0.1]: Connection timed out
    Jul 2 17:34:38 sentora postfix/smtps/smtpd[28425]: lost connection after CONNECT from localhost[127.0.0.1]

    You have commented out the submission line
    Code:
    #submission inet n - y - - smtpd
    Compare what you have in that file to the ISPConfig Perfect Server Guide. And while at it, check all other setting also.

    I did all that explained in the guide, but now it doesn't let me access ISPConfig via the web. Do I have to recreate the database ?? And where do I put it?

    In what way does it fail, exactly?
    Does
    Code:
    systemctl --state=failed
    now show all services are running?
    Is the htf_report now OK?

    Why did you not reveal that first thing?
    Do what error message says, and check mysql config. You may have error messages in logs to help figure out what is wrong. If not, just check what you configured to the Perfect Server Guide.
