I am just wondering if I miss the point, but how can I configure my system (ubuntu 6.06 TLS) to use zimbra for local email? For example system cron jobs reporting to root? I already set aliases (therefor I had to install postfix and disable it) for root = email@example.com, domain.com handled by zimbra. but this does not the trick.
Although the zimbra cron jobs does not email to a zimbra admin account and after each update I have to fix this manual.
Any suggestions how to get this smooth?
