Red Hat 7.2++++, gcc 3.0.4
Actually, I just wanted an excuse for pointing out how fantastic Exim
is, again (just managed a fresh "LDAP doggy jumps through new hoop".)
January last I decided to upgrade from 3 to 4. It *was* trivial.
With the 4.1x download, you get a perl script,
./build-version/convert4r4. With it you can convert most of your v3
configure config file to v4. It seems to take "outputfile inputfile" as
arguments. It makes some mistakes, but not many.
If you only have the one machine to practice on, you run a test server
on another port, for ex. in the Exim v4 main configuration:
local_interfaces = 0.0.0.0.9009
Or you don't even have to run it as a daemon, just in -d (debug) mode,
with its v4 config file given by '-C /path/to/v4config/file'. Then it
doesn't run as a daemon.
Then you open the supplied spec.txt (all the html documentation on the
web is useless, the pdf or ps suchlike is better) in your exim build
directory and read it thoroughly, then you start trying things out.
Honestly, there's no better way. You have to keep on going back to the
spec.txt doc, though, and trying tings out.
Consult the mail list archives after Jan. 2002 often, since most
questions you'll have have been answered there. I have everything since
Nov. 15th last on my hard disk.
After a while, you'll have gone over to Exim 4 and feel pity on those
who haven't.
Best,
Tony
