Bug#284755: exim4: Default localhost description in /etc/hosts causes Exim to send HELO localhost.localdomain

[Ivar Zarans]

Package: exim4
Version: 4.34-8
Severity: important

When /etc/hosts has localhost described as (default in Debian Sarge):
127.0.0.1       localhost.localdomain   localhost

then Exim uses "localhost.localdomain" as name in HELO command. Some
mailers are rejecting connections with incorrect hostname as HELO
parameter.

Rewriting /etc/hosts localhost entry as:
127.0.0.1       localhost

fixes this problem, but Exim should handle default /etc/hosts properly.
