Hi there, I have noticed a bad behavior of exim or something exim calls several month ago and it still seems to exist:
exim does a DNS lookup of localhost each time it is called instead of using /etc/hosts. On dial on demand systems this is really harmfull as a connection is established with each exim queue run (normally every 15 minutes) and stays on until an idle timeout only to be restablished again a few minutes later. This could be really expensive for people who have to pay per minute! There was a discussion about this with Philip Hazel (exim developer) at that time: http://www.exim.org/pipermail/exim-users/Week-of-Mon-20011105/031907.html The DNS lookup seems to be invoked by a gethostbyname() call. As I was not interested in DoD at that time I dropped the issue without solving it and hoped it will disappear without special attention. There is already a bug report about it as well. However, it does not say anything about DoD: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=96633&repeatmerged=yes As hinted by Kevin Tappe this could be caused by a (resolved?) libc6 bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=118364&repeatmerged=yes Maybe the libc6 issue is resolved for DNS A entries, but not for DNS MX entries? Barry Mathieu has asked recently for help with this issue on debian-user and I guess the more people switch over to woody the more people will complain ... I do not know if I am mailing to the right list/people to get the required attention, but if not please forward this mail to the right place. Thanks in advance for your help.
