    Hi, i update ISPConfig from 3.15p to 3.2 and after this I can send mails but I can't receive mails anymore

    I always test my mail server with a gmail account and before the update to 3.2 it worked.

    When I look in the mail.log I find this:
    Oct 22 18:15:49 mail postfix/smtpd[5395]: NOQUEUE: reject: RCPT from mail-lf1-f53.google.com[209.85.167.53]: 451 4.3.5 Server configuration error;
    Can someone help me to solve this problem

    Thanks

    Are there more lines around this error?
    Code:
    grep 5395 /var/log/mail.log
    Post "postconf -n" and your master.cf

    Can you run

    postfix check
    ?

    The output postfix check is.

    Did you reconfigure services? If not, run the update again and choose y for reconfigure services (this will overwrite custom config, so make a backup at the beginning of the script):
    Code:
    cd /tmp
    wget https://www.ispconfig.org/downloads/ISPConfig-3.2.tar.gz
    tar xvfz ISPConfig-3.2.tar.gz
    cd ispconfig3_install/install
    php -q update.php

    Would you mind sharing the lines with us? ;)
    You have modifications from the standard ISPC options. Save your main.cf and master.cf in a safe location and do "reconfigure services" (you can do 'selected' and only reconfigure postfix/mail). This should give you a working system. Then compare (diff) the old and new config and read the documentation if you had some modifications that you still need. (For example, do you really need tls1.0 for your users?)

    Yes I dit reconfigure services. I update again and choose y for reconfigure services.

    The same problem.

    Do you have a custom config for Postfix in /usr/local/ispconfig/conf-custom/install ?
    It seems like your config is not propagated with the changes from 3.2.

    Could you share the contents of your main.cf?

    My bad, I meant /usr/local/ispconfig/server/conf-custom/install

    Well, the error was clearly stated in the error message. Look at that line in your config ...
    Either the reconfigure service does not work or there is an bug in ispconfig which created that line ..
    Remove the "array"s

    In directory install is only one file named "empty.dir" with the text "This empty directory is needed by ISPConfig."

    Lol I oversaw that as I kind of got a tunnel vision :oops:

    It could be that there's a bug, we have to check that for sure.

    @Robin.k, I may have missed it while (re)scanning this post, but what OS are you running?

    Hi, after the upgrade to ISPConfig I have more "mail-warn logs"

    mail dovecot: config: Warning: service auth { client_limit=1000 } is lower than required under max. load (1012)

    How to solve this warnings?

    Thanks
