Meh?

I haven't looked at the docs for Net::SMTP, but this just looks weird to me.

What you're creating within @list is an array wherein the 0-th element is
itself a listref.

Then, you pass a _reference_ to this list?

I would think that what you'd want is...


@list = ('1.2.3.4', '2.3.4.5');
Net::SMTP->new(\@list, ...);

I.e. if Net::SMTP wants a listref, it probably doesn't want a double
listref.
