Package: exim4-daemon-heavy
Version: 4.89-2+deb9u2
Severity: important

Dear Maintainer,

Due to an error in the Avast protocol E-Mails that cannot be scanned from Avast (eg: password protected ZIP, and so on) result
in "blackhole" and will be sent again.

The problem has already a solution contained in these patches of Exim:

91e974f5 Avast: rework interface
eb445b04 Avast: implement pass_unscanned option
ad93c40f Avast: improve compliance with avast-protocol(5)
71bb51e0 Update to protocol used by avast 2.2.0 (Multiline responses) (Bug 2112)

The version 4.91 of Exim already include them.
It will be nice if they will be backported to the version 4.89, distributed in Debian 9.

Thanks a lot
Luca Bertoncello
