You're not building with HAVE_ICONV=yes perhaps? And then are doing
some system filter check which fails? Or you built Exim with HAVE_ICONV
but HEADERS_CHARSET which doesn't include support for the iso-8859-1
characters you're seeing (eg, US-SASCII)?
Perhaps logs would help, or an entry from paniclog, or the result of
looking at { exim -d -oX 26 -bd } output when you telnet to port 26 and
use SMTP to send a copy of such a mail, pasting in the bad subject?
If I create a file "foo.eml" containing:
----------------------------8< cut here >8------------------------------
From: Phil Pennock <exim-users@???>
To: Phil Pennock <exim-users@???>
Subject:

and then invoke { exim -bem foo.eml } then:

Decodes just fine here.
