Hello!
I am running latest version of toaster and had a client run into the
qmail-dk signing issue last night – with only one email recipient. He
tried multiple times to send the email – same thing.
“554 qmail-dk: Cannot sign message due to invalid message syntax. (#5.3.0)”
There are very rare (unidentified) circumstances where this error occurs.
Is it still best practice to unlink qmail-dk and use qmail-queue.orig?
TTBOMK, yes.
Is there a good way to use DKSIGNing? I found a reference to some
scripts by a Kyle Wheeler.
http://qmail.jms1.net/patches/domainkeys.shtml
JMS recommends *not* patching qmail to implement DK. Kyle's method uses
perl scripts, which is much more flexible.
See http://www.memoryhole.net/qmail/#dkim
I haven't implemented Jake's DKIM scripts yet personally. I suspect
they're the same as Kyle's, but I'm not sure. Would someone care to
compare these with what Jake's video uses and verify if they're the same
or not? If they're not the same, I'd like to see a comparison.
is DKSIGNing necessary or suggested? Is qmail-dk now reliable and
something different caused the issue with this one recipient address?
<opinion>
If DK isn't yet deprecated, it probably should be. DKIM is preferable.
</opinion>
DKIM is not required. It *may* affect deliverability to some
destinations, but I'm not sure to what degree. Someone else may have
some experiences to share in this area.
