Thanks. It was the installation of IO::SSL that caused the breakage in SMTP ( Default SSL_verify_mode deprecated ). I Googled around and found that if you replace that regex, it will fix SMTP, but it appears to have broken LWP. I tried to get the debug info like you suggested, but when I added the envrionment variable (from shell and in a begin block in my script), nothing was output. /usr/share/perl5/vendor_perl/IO/Socket/SSL.pm our $VERSION = '1.94'; /usr/share/perl5/LWP.pm $VERSION = "6.05";
