Version: 4.63-17
Severity: important
Tags: patch ipv6
The configuration template at /etc/exim4/exim4.conf.template is not
capable of handling IPv6 smarthosts with SMTP authentication.
The following section does a lookup in /etc/exim4/passwd.client and (if
found) returns the $host_address value in the hosts_try_auth list:
---cut---
remote_smtp_smarthost:
debug_print = "T: remote_smtp_smarthost for $local_p...@$domain"
driver = smtp
hosts_try_auth = ${if exists{CONFDIR/passwd.client} \
{\
${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$host_address}}\
}\
{} \
}
---cut---
If $host_address is an IPv6 address, the colons are interpreted as
address seperators. To use an IPv6 address, the hosts_try_auth list
should start with "<; ", thus only a semicolon will be used as seperator.
FIX:
- hosts_try_auth = ${if exists{CONFDIR/passwd.client} \
+ hosts_try_auth = <; ${if exists{CONFDIR/passwd.client} \
Best regards,
Klaus Keppler
