Bug#462173: exim4-config: bashism in update-exim4.conf

[Michal Politowski]

Package: exim4-config
Version: 4.69-1
Severity: serious
Justification: Policy 10.4

update-exim4.conf does not work if /bin/sh is dash

The preprocess_macro function uses the non-POSIX behaviour of echo in bash,
which does not interpret escape characters by default.
In dash the '\n's are POSIX-ly correctly replaced with newlines
which causes the subsequent sed to fail with unterminated 's' command.
