Do you mean do you need anything special to upgrade from 3.35 to 4.30? If
so, yes: the Exim 3 -> Exim 4 upgrade is a non-trivial one, although you
shouldn't be scared off by it as it's not too bad, plus Exim 4 is so much
more powerful and flexible than Exim 3. Read the documentation and you'll
find that amongst other things, there's a handy utility to convert your
Exim 3 config file to Exim 4.

This is only necessary if you're going to use SSL (a good idea if you're
using AUTH PLAIN; not quite so important if you are only going to do AUTH
CRAM-MD5). In that case, you should probably familiarise yourself with SSL
in general (and also your chosen SSL library - probably OpenSSL or GnuTLS)
before attempting to get Exim to use it. I'm not sure of the best starting
place for SSL in general, but I'm sure a web search will turn up plenty of
resources to look at.
