Hello,
I have a problem while signing emails with domainkey : a lot (30%) of
emails are not signed before the first try, and Yahoo really don't like
this.
From logs, this email is not signed :
2008-08-12 00:00:04 1KSfQq-0004aF-Cd <= ***@domain.tld U=mailer1 P=local
S=48162

2008-08-12 00:10:49 1KSfQq-0004aF-Cd Spool file is locked (another
process is handling this message)

But this one is signed :

Both emails are for a valid user at "yahoo.fr", and from the same local box.
This is the "remote_smtp" transport :
dk_canon = nofws
dk_selector = default
dk_private_key = ${lookup {$domain} nwildlsearch {/etc/exim4/dk/domains} \
{/etc/exim4/dk/rsa.private.$dk_domain} {0} }
I signed emails only when there are for some destinations (yahoo and
gmail for example).
I used a "customized" amd64 version of the Debian exim4 package (4.68-2
from backports), on which I only enable sqlite and domainkeys.
The libdomainkeys used is the version 0.68-1 : I wasn't able to build an
amd64 package of the version 0.69.
Does the problem is due to my version of libdomainkeys ?
Thanks in advance,
Olivier Bonvalet
