delivery temporarily suspended: connect to, localhost[10.11.12.13]:25: Connection timed out

[Admin]

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:
