Hi folks,

I am in quest for perl wisdom, here...

I have an error when parsing a DKIM-signed message, which I don't fully understand.

First, here are the logs I obtain when spooler.pl processes a DKIM-signed message:

Erreur de segmentation (Note; this means "segmentation fault") Indeed the module "Crypt::OpenSSL::bignum was not installed. But it is not required by Crypt::OpenSSL::RSA. It is not event listed in the dependencies and the line where it is required is enclosed in an eval{}, like this:

BEGIN { eval { require Crypt::OpenSSL::Bignum; }; }

So, on my opinion, the process should not crash when Bignum is not found. That's what this eval is doing.

So, how comes the spooler.pl crashes?

Best regards,

David
