Exim: Previous (cached) callout verification failure

Wednesday, April 25th, 2007

When testing routing behavior in Exim, remember to flush the callout cache. If an address callout has failed, that failure will be cached to speed up routing should another email arrive for that address. This is normally a good thing, but a pain if you’re testing configs because you’ll keep getting the address rejected even if you’ve fixed the routing problem. 

rejected RCPT <joe@bloggs.com>: Previous (cached) callout verification failure

There are two solutions.

The first is to turn off callout caching using the no_cache option in exim.conf. eg:

verify = recipient/callout=no_cache

or you can flush the callout cache. Simply -HUPing or restarting exim won’t do. You need to delete the cache manually:


cd /var/spool/exim/db
mv callout callout.deleted  # or just delete it

Debian Etch Released - Changes to /etc/apt/sources.list

Monday, April 9th, 2007

When my grandfather was a boy, back in the days when everything was black and white, he waited up all night so he could witness the release of Debian Sarge. Now I, too, can say I’ve witnessed the release of that Halley’s Comet of distros, a new Debian Stable…

Debian 4.0 (Etch) became the stable version of Debian yesterday. If you’ve been using Etch prior to this, you will need to add security updates to your sources.list:


#
#  /etc/apt/sources.list
#

#
# etch
#
deb     http://ftp.uk.debian.org/debian/     etch main contrib non-free
deb-src http://ftp.uk.debian.org/debian/     etch main contrib non-free

#
#  Security updates
#
deb     http://security.debian.org/ etch/updates  main contrib non-free
deb-src http://security.debian.org/ etch/updates  main contrib non-free

Running apt-get update you may run into these errors:


W: Conflicting distribution: http://security.debian.org stable/updates Release
     (expected stable but got etch)
W: You may want to run apt-get update to correct these problems

Check your sources.list file again, and explicity use “etch” instead of stable as on some mirrors they don’t seem to be the same thing, yet. Then re-run apt-get update.

Welcome to Debian 4.0!
