Hi,

Operarting System: Ubuntu 10.04 Lucid.

After upgrading from zcs-6.0.10 to zcs-7.1.0, some crontab tasks stoped sending email.

The problem was that the symbolic link in /usr/sbin/sendmail was pointing not to the soflink postfix in /opt/zimbra, but to the specific postfix implementation of 6.0:

lrwxrwxrwx 1 root root 42 Sep 26 2010 /usr/sbin/sendmail -> /opt/zimbra/postfix-2.6.7.2z/sbin/sendmail

the fix was:

sudo rm /usr/sbin/sendmail
sudo ln -s /opt/zimbra/postfix/sbin/sendmail /usr/sbin/sendmail

o

sudo update-alternatives --install /usr/sbin/sendmail mta-sendmail /opt/zimbra/postfix/sbin/sendmail 25

Ant that should fix it for now and the next upgrades.
