I have put Exim 4.21 on the ftp site:
ftp://ftp.csx.cam.ac.uk/pub/software/email/exim/exim4/exim-4.21.tar.gz
ftp://ftp.csx.cam.ac.uk/pub/software/email/exim/exim4/exim-4.21.tar.bz2
eed92d34e02a5de1493d766fc92b0c94 exim-4.21.tar.gz
16b1290e4c289c7d70294ca447b0a3bc exim-4.21.tar.bz2
Although the version number has increase only by 0.01, there are quite a
lot of changes in this release[*]. For those who don't know the way Exim
version numbers work: the first decimal digit doesn't change until the
documentation is fully updated. For this release, the new features are
described in the doc/NewStuff file. All changes are listed in
doc/ChangeLog. You should also read README.UPDATING before updating.
