Subject: | Uninitialized $mailer in Email::Send::Sendmail |
The Email::Send::Sendmail::send() method has this code:
my $mailer = $class->_find_sendmail;
return failure "Found $mailer but cannot execute it"
unless -x $mailer;
But _find_sendmail() can return undef, which causes uninitialized
warnings for the string interpolation and for the -x.
