I tried exim4 start, but now I get this error:
lookup type "mysql" is not available. I installed exim4 with apt-get install exim4. How can I fix this?

mysql has to be compiled in to be available as a lookup type. You can see what lookups are available by running exim4 -bV (or exim, or sendmail, or however your exim binary is actually named). Here's an example output from one of my servers (note I don't have mysql compiled in either):
g3 0 /home/jj33 > exim -bV | grep ^Lookup
Lookups: lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmnz dnsdb dsearch passwd
I seem to remember that Debian (and therefore probably Ubuntu) had something like exim4-heavy as a package, which was exim with all the bells and whistles compiled in. You might take a look at that. I also seem to remember that some of the packagers maintained their own private dynamic loader for lookup types, so it might be possible in Debian/Ubuntu that you could load the exim4-mysql package or some such and have the lookup available.
