Hi there,

I am using fetchmail to pop3 mail from gmail. But when I receive email
I find that fetchmail is using postfix to deliver the mail to the
corresponding internal mailbox. postfix responds with the following
error and best I can tell the mail never ends up in my inbox. Looks
like localhost is considered 10.11.12.13. The error message,
/etc/hosts, and postconf -n are below.

Here is the error message:

it looks like you are a victim of ${yourself} + ${debian package}.

- debian package enables chroot by default
- debian package disables append_dot_mydomain
- you removed localhost from mydestination
- you used localhost in fetchmail configuration

a quick fix would be to add localhost to mydestination.

but
- you should also disable chroot (edit master.cf and set the 5th field
to 'n') until you feel ready for chrooting.
- find out why you get 10.11.12.13 for localhost. if this is returned by
your ISP DNS server, then get far away from such a server.

In general, we ignore these as well as errors showns in a mailer... etc.
we prefer _logs_.

It has something to do with GPRS. There are plenty links if you just
google for the IP.

huh? general packet radio service? I dont get the connection. The
postfix server is running on a server housed in a rackspace.com colo
facility.

10.11.12.13 is also the IP of localhost.com. Is it possible you have no
localhost entry in /etc/hosts, causing your machine to look up
localhost.com?

THANKS VERY MUCH. It's enough to have .com default domain suffix and it
explains some weirdnessess ;-)
