Bug#629117: exim4-config: Malformed IP address ":1" in local_interfaces

[Paul van Genderen]

Package: exim4-config
Version: 4.72-6+squeeze2
Severity: normal
Tags: ipv6

When configuring exim4, the IPv6 localhost cannot be used as the
local_interfaces setting because it removes colons. Furthermore,
if one would expand the address like so: 0000:0000::1, only the
first segment is kept. The standard method of explicitly denoting
an IPv6 addresses in brackets is not accepted either.

Some examples:

Answer          Result
__________________________________________________________________________
::1             Malformed IP address ":1" in local_interfaces

[::1]           Malformed IP address ":1" in local_interfaces

0000::1         Malformed IP address "0000:1" in local_interfaces

[0000::1]       Malformed IP address "0000:1" in local_interfaces

0000:0000::1    Malformed IP address "0000" in local_interfaces

[0000:0000::1]  Malformed IP address "[0000" in local_interfaces

The workaround is to append a semicolon to the address. Kill any running
exim4 process, remove /var/log/exim4/paniclog if it exists and configure
"::1;" as the IP address to listen on.
