All,

I have found a bug that's been bugging us (guess thats why they call 'em
bugs).
In version 1.2, variables.pl:

  $AUTH_METHOD = "POP"; # possible values: (FTP|POP)
  if ($AUTH_METHOD = "POP") { use Mail::POP3Client; }
  if ($AUTH_METHOD = "FTP") { use Net::FTP; }

the problem is in the if statements...it's not using the comparison
operator, it's using the assignment operator.

The reason this is a legal statement is because the evaluation of an
assignment is true.

It should be:

  $AUTH_METHOD = "POP"; # possible values: (FTP|POP)
  if ($AUTH_METHOD == "POP") { use Mail::POP3Client; }
  elsif ($AUTH_METHOD == "FTP") { use Net::FTP; }

NOTE: the second 'if' should really be an 'elsif' since there is no
reason to evaluate it if the first 'if' statement is true.

This will be fixed in the next version...we were wondering why NetReg
was using FTP to authenticate instead of POP. It was because the second
'if' was setting
$AUTH_METHOD equal to FTP.

Sorry.

-peter
