I apologize for the interruption in this thread, fires to put out so slow
getting back to this.

It appears postfix was installed as a result of a mysql
installation:
aptitude why postfix: i automysqlbackup Depends

mailx i A bsd-mailx Depends default-mta |

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.

The Debian configuration that Ubuntu inherits does have an option to
not configure postfix when installed. This is intended to be used
by an admin that intends to do their own configuration from scratch.
It is not intended to be left that way indefinitely.
Unfortunately, when postfix is installed as a package dependency of
some package that wants a local MTA installed, people don't always
configure it. Since postfix is the default MTA in Ubuntu (it's not in
Debian), that means it is not unusual to find Ubuntu installations
with postfix that are not well configured because it was only
installed as a side effect of installing some other package.
The advice to use dpkg-reconfigure to set up the basic postfix
installation (that you may then further configure) is the correct
approach here.
Thanks, that probably explains what's going on.
I ran dpkg-reconfigure postfix but that didn't solve the problem:
$ sudo dpkg-reconfigure postfix
setting synchronous mail queue updates: true
changing /etc/mailname to xbiologix.net
setting myorigin
setting destinations: xbiologix.net, $myhostname,
xblgx-ops.c.insidexblgx.internal, localhost.c.insidexblgx.internal, localhost
setting relayhost: aspmx3.googlemail.com.
setting mynetworks: 127.0.0.0/8
setting mailbox_size_limit: 51200000
setting recipient_delimiter: +
setting inet_interfaces: loopback-only
setting inet_protocols: ipv4
Postfix is now set up with the changes above. If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).
After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

-------------
I had previously edited main.cf to set
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
$ sudo postfix check
postfix: fatal: bad string length 0 < 1: mailq_path =
Not sure what mailq_path should be set to... /var/spool/postfix/ ?
Do all of these need to be set? I thought the re-configure should
have taken care of this, and reasonable defaults would be applied?
Do I need to remove main.cf before doing a dpkg-reconfigure?
Thanks,
Gary
