linxdev has asked for the wisdom of the Perl Monks concerning the following question:

After and upgrade of perl sending mail via my mail relay is failing. I suspect this has to do with an invalid certification because my test program works fine for sending to gmail.

Here is my strace output:

I am using:

my $s = Net::SMTP::SSL->new('192.168.100.1', Port => 465, Debug=>1) or + die "$!";

I never get far enough to see a failure so I had to use strace.

Is this a certificate issue?

    Did some stracing.

      I guess your certificate is not signed by any of the trusted CAs on the system. Thus the verification will fail, because there is not trust anchor. In old times (before 1.950, released 07/2013) the default was to not verify the certificate which is of course a bad idea for a default when doing security relevant stuff.

        Yep, I changed that code. These devices run on LANs with multiple interfaces.
