postfix install error: fatal file /etc/postfix/main.cf: parameter setgid_group: unknown group name: postdrop
Hi,
sys: Centos 5.2 x86_64
Trying to switch from sendmail to postfix I did:
# yum remove sendmail
which resulted in erasing of: mdadm sendmail-doc sendmail sendmail-cf mutt fetchmail redhat-lsb
I did then:
yum -y install redhat-lsb.x86_64 postfix
and got this error:
Installing: postfix ######################### [1/2] postfix: fatal: file /etc/postfix/main.cf: parameter setgid_group: unknown group name: postdrop warning: group postdrop does not exist - using root warning: group postdrop does not exist - using root warning: group postdrop does not exist - using root warning: group postdrop does not exist - using root Installing: redhat-lsb ######################### [2/2]
I checked and indeed there is no group postdrop on the system. On an El5 system I see the group.
Thx Rainer

Are you using any sort of network authentication system like NIS or LDAP? Or just standard local files?

No NIS or LDAP, plain local files.

I haven't tried CentOS 5.2 yet(keep seeing reports of issues), postfix in 5.1 worked fine for me and in 4.x. I suggest just adding the group manually and removing/re-installing the postfix rpm. Perhaps there is a bug in the 5.2 RPM that doesn't add the group correctly for some reason.
What I'd probably do is just copy/paste the postdrop entry from the other system's /etc/group file to the system that doesn't have it.
I use the same password/group/shadow files across CentOS 4, 5, and FC8 (and in the past FC4, and FC5) so the UIDs/GIDs are pretty compatible.

You don't need to remove sendmail, you can just use system-switch-mail to set postfix as the MTA.
There is documentation on setting up a basic postfix server (on CentOS 5) on the Wiki here:
Thx for your answer.

I knew that thx. I tested the exact same steps on our internal testmachine. Must admit it has EL5.2 x86_64 on it but did not show this behaviour.

Ok, think I found the cause...
The server I try to install to has heartbeat/cluster software installed. I already has a group with GID 90: # grep 90 /etc/group haclient:x:90:
The postfix rpm has hardcoded: /usr/sbin/groupadd -g 90 -r postdrop 2>/dev/null
So that's the reason I get the messages...
Thx for all your help Rainer

Makes sense then, where did heartbeat/cluster software come from? If it's a supported package on RHEL-based systems it shouldn't add a user or group with a conflicting ID.

It's from the LinuxHA/Pacemaker project which has its own repo build by OpenSuse build service.
