Assunto: [Exim] Problem with unqualified rcpt after upgrading 3.35 -> 4.14
Hi all,

today I setup and compiled the current release of Exim (4.14) on a Debian
3.0 box in order to replace the Debian stock version 3.35 as I need some
features of the new version.
I used the "convert4r4" programm to upgrade the config script which _should_
be fairly ease as my configuration (allways-up-DSL with some dynamic DNS)
is quite straight forward (I though of at least <g>).
The main domain is "all-about-shift.com". The result of the upgrade is that
it is now possible for a external MTA to send a mail a'la

    rcpt to: <"spamtest@???>


which wasn't the case with the 3.35 version. Although relaying is not
allowed at all it opens a small hole for a spammer to flood my server.
While the above command results in an accepted mail with exim4 it resulted
in a rejected in 3.35.
I tried various settings to change but nothing fixed this issue. My config
file is included, any help is greatly appreciated.



Thanks,
Soren Gerlach
