[Pkg-exim4-users] Upgrade re-accept question

[Wm. Josiah Erikson]

I think this is more like a dpkg usage question, but I can't find the
answer on google or in the manpage or in the documentation it's pointing
me to. It's pretty much, I think, the simplest question one could have
about this situation...
So I upgraded exim4 and I got the errors that everybody knows so well:

Setting up exim4-config (4.69-2) ...
DEBCONFsomethingDEBCONF found in exim configuration. This is most probably
caused by you upgrading to exim4 4.67-3 or later without accepting the
suggested conffile changes. Please read
/usr/share/doc/exim4-config/NEWS.Debian.gz for 4.67-2 and 4.67-4
2009-04-07 11:11:09 Exim configuration error in line 32 of
/var/lib/exim4/config.autogenerated.tmp:
  malformed macro definition
Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not
installing
/var/lib/exim4/config.autogenerated.tmp to
/var/lib/exim4/config.autogenerated
dpkg: error processing exim4-config (--configure):
subprocess post-installation script returned error exit status 1

....but how do I re-run the script so that I can accept said proposed
changes? It's true I didn't accept them the first time.... I usually
don't accept changes to files that I changed myself, because it tends to
break my config, but clearly in this case I made the wrong choice.
Thanks,
