Package        : libmail-dkim-perl
Version        : 0.54-1+deb10u1
Debian Bug     : 1039489

It was discovered that the domain check in libmail-dkim-perl, a Perl module to
cryptographically identify the sender of email, compares i and d tags case
sensitive when t=s is set on the DKIM key which causes spurious fails of
legitimate messages.

For Debian 10 buster, this problem has been fixed in version

We recommend that you upgrade your libmail-dkim-perl packages.

For the detailed security status of libmail-dkim-perl please refer to
