[Pkg-exim4-users] dc_minimaldns not working?

[Lothar Ketterer]

Dear all,

exim4-daemon-light is running on my single-user desktop with Debian
Etch. It was configured using debconf, resulting in the following
update-exim4.conf.conf:

dc_eximconfig_configtype='smarthost'
dc_other_hostnames='apothekerknecht2'
dc_local_interfaces='127.0.0.1'
dc_readhost='staff.uni-marburg.de'
dc_relay_domains=''
dc_minimaldns='true'
dc_relay_nets=''
dc_smarthost='smtp.staff.uni-marburg.de'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='true'
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

Note that changing the appropriate line to

dc_other_hostnames=''

doesn't change the behaviour described below.

Internet is accessed by a DSL connection, managed by a box with
integrated DSL modem/WLAN AP/NAT functionality. This box establishes a
connection whenever someone tries to access the net. Therefore, the
"minimize dns lookups" question was answered with yes.

Unfortunately, this doesn't keep exim4 from doing DNS lookups every time
the machine is booted. My understanding from the information given in
the debconf question as well as in README.Debian.gz is that it really
should keep exim4 from doing this.

I know that "apothekerknecht2" (my hostname) is not a fully qualified
domain name, so could this be the problem?

In the meanwhile, i could solve the problem by creating
/etc/exim4/exim4.conf.localmacros with a content of

dns_ipv4_lookup = *

as suggested in the FAQ.

Still i would be interested why dc_minimaldns is not working in my case.
Do you have any ideas?

Best regards,
Lothar
