Hi guys,

I successfully upgraded to from Zimbra 5.0 to 6.0.6 except that postfix now refuse to start. All other service looks fine though. Here's the error when zimbra is start;

Starting zmmtaconfig...zmmtaconfig is already running.
postalias: fatal: bad string length 0 < 1: setgid_group =
postfix failed to start

it seems that postalias fail to build the aliases map because setgid_group is not set in main.cf

I tried to issue this command to fix main.cf;
postconf -e setgid_group=postdrop

It fix it but when zimbra is restarted main.cf is overwrite with a version that set setgid_group to null

I then check zimbra local config with;
zmlocalconfig -s|grep setgid_group
setgid_group = postdrop

So it looks properly set. I confirmed it by looking at localconfig.xml;

<key name="setgid_group">

Looks good too, I then look at my latest config files (./config.397);

I'm pretty mazes... Anyone knows which process overwrite /opt/zimbra/postfix/conf/main.cf ?

I monitored main.cf and it seem to be overwritten when mailboxd start but I'm not sure...

Thanks in advance!
