Not weird at all. Your problem is most likely right here:
> @digOut = `dig [EMAIL PROTECTED] $mx`;
take a look at the foreach section of the perlsyn (perl syntax) man
page. you should read the whole thing if you're having these kinds of
trouble (actually, you should read it anyway), but the relevant bit
for the moment is:
"If any part of LIST is an array, foreach will get very confused if
you add or remove elements within the loop body, for example with
splice. *So don't do that.*"
Or in this case, by replacing the entire array with new output from
dig in the subroutine.
Aha! thank you so much. using a different array var in the subroutine
did indeed fix it.
HTH,
