    Exclamation Dovecot 1 to 2 broke mail system. Help :-(

    During the upgrade to Dovecot 2 something has gone wrong and I have spent many hours trying to fix :-( In the mail.log file I know get the following errors

    Jul 7 19:10:14 mail dovecot: master: Dovecot v2.0.13 starting up (core dumps disabled)

    I don't know a solution, but if you want to have your mail up and running asap, you could consider going back to dovecot 1.

    cd /usr/local/directadmin/custombuild
    perl -pi -e 's/dovecot:2.0.13:fd8a0702275a61332db7353dadff0f92/dovecot:1.2.17:a2c01cb0a9c54302d0870fdc3e6d2106/' versions.txt
    ./build dovecot
    If you lost the dovecot 1 config, get it here http://files.directadmin.com/service...d/dovecot.conf

    wget -O /etc/dovecot.conf "http://files.directadmin.com/services/custombuild/dovecot.conf.2.0"

    /sbin/service dovecot restart

    You probably have another OS, maybe /etc/init.d/dovecot restart will work. But it seems that config file is the same one you just pasted.

    I'd just go back to dovecot1..

    Thanks, if I go back to dovecot one then my CPU is constantly at 100% which is why I thought about the upgrade to 2....

    On Version 1 when i run the top command i get the following:

    When dovecot takes so many CPU and has many childs, do you see anything unusual like an attack in mail.log?

    if not then maybe someone else can help.

    You might need someone to look at your server. That is very strange.

    Did you try:

    cd /usr/local/directadmin/custombuild
    ./build update
    ./build clean
    ./build dovecot d
    wget -O /etc/dovecot.conf "http://files.directadmin.com/services/custombuild/dovecot.conf.2.0"

    /etc/init.d/dovecot restart

    If that doesnt fix it then something else is definately screwed up somewhere.

    You might want to try running dovecot in the foreground with:

    dovecot -F

    To sync your time do:

    ntpdate -u pool.ntp.org

    Also put this in /etc/crontab

    */5 * * * * root /usr/sbin/ntpdate -u pool.ntp.org >/dev/null 2>&1

    http://support.ntp.org/bin/view/Servers/NTPPoolServers

    Find a server that is closer to where your server is.
