I modified /etc/crontable to fire off some backup stuff (a shell
script that does a "gcloud compute disks snapshot ...". Cron logs
attempting to start the script, then logs: cron[1214]: sendmail:
fatal: bad string length 0 < 1: setgid_group =
postfix/sendmail[8628]: fatal: bad string length 0 < 1:
setgid_group =
As I did not set this system up, it's not clear to me what has
been properly installed and what came as a result of other stuff.
Initially, I was getting a "/etc/postfix/main.cf: No such file or
directory" error. I copied main.cf.proto to main.cf without
change, as it seemed to be ok as is.
It appears postfix was installed as a result of a mysql
installation:
aptitude why postfix: i automysqlbackup Depends bsd-mailx |
mailx i A bsd-mailx Depends default-mta |
mail-transport-agent i A postfix Provides
mail-transport-agent
but the setup not completed? This machine is not intended to
serve as a mail server; I only need it to post mail appropriately.
I modified /etc/aliases to forward root, then tried sudo
newaliases but I get the same error: newaliases: fatal: bad string
length 0 < 1: setgid_group =
you should try to run:
dpkg --configure -a to configure all packages that aren't configured
yet.
however, so far this problem looks more like ubuntu than postfix
problem.

Please DO follow a proper Postfix installation procedure.
- Either install from package.
- Or install from source code.
This is not something that you should be fixing by hand.
Thank you both. Before doing something stupid...
This system has been running in a production environment for
some time, although what the mail situation has been I'm not sure.
The production environment involves a redmine installation.
The postfix package was already installed, which is what troubles
me; it was apparently not properly configured. Will an attempt to
reconfigure an already installed and configured package screw
things up? Perhaps it was configured automatically by the
mysqlbackup install?
