Maybe I can help:
In my /etc/exim/exim.conf, I have:
Of course, in my ROUTERS section, I have my smarthost defined:
# Send all mail to a smarthost
smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* mail.duo-county.com bydns_a"
Then in my REWRITE configuration, I have:
######################################################################
# REWRITE CONFIGURATION #
######################################################################
# There are no rewriting specifications in this default configuration
# file.
# This rewriting rule is particularly useful for dialup users who
# don't have their own domain, but could be useful for anyone.
# It looks up the real address of all local users in a file
#*@localhost.localdomain ${lookup{$1}lsearch{/etc/email-addresses}\
# {$value}fail} frFs
dlb@??? dbree@??? Ffrs
Note that in the above, since I have only one user, I have commented out
the file lookup function and simply have the single substitution. If
you have more than one user, or email address, you probably should use
the file (/etc/email-addresses). There are (commented-out) examples of
how they should be entered.
Of course, you'll have to use fetchmail to retrieve your mail from the
server.. If you don't have this set up, do you have a program called
'fetchmailconf' ? This can set up your fetcmail for you, but my
~/.fetchmailrc looks like this:
# Configuration created Fri Aug 23 22:33:22 2002 by fetchmailconf
set postmaster "dlb"
set bouncemail
set no spambounce
set properties ""
poll mail.duo-county.com with proto POP3
user 'dbree' there with password secret is dlb here
I then run fetchmail from the command line. If you are using something
else such as Kmail now, ( didn't look at your header before beginning
this reply), you can first run the command 'fetchmail -k' to retrieve
your mails, but not delete them from the server, and then get your mail
with whatever you have been using and check to see that none were lost.
