Comment 2 for bug 721320

1. Better explanation of the issue and how it is affecting the package in Ubuntu.

The debian bug report explains it quite nicely, but let me summarize...

Without this patch, the Exim4 package on Lucid will generate warnings like this

2010-01-31 21:41:16 1Nbga6-0005ZL-FH DKIM: Error while running this message through validation, disabling signature verification.

in /var/log/exim4/paniclog.

These are not 'real' errors, they are just warnings. They can not be disabled. They do not belong in the paniclog, which should always be empty.

2. Provide a step-by-step to be able to reproduce this bug.

Run a semi-busy mailserver on Lucid, and you will collect these warnings in your paniclog - on one of our machines, I'm seeing a couple a day on an average mail volume of 100,000 accepted messages.

The patch is trivial, it's been applied to the Debian package, and it would be really nice to not have to manually patch Exim4 on Lucid for this.
