Good idea. Here is the block of code:

  $message =~ s/<REQUEST>/$requests/i;
  $sitecfg{SUBJECT}=~s/<NAME>/$htmlparams{name}/i;
  my %mail = (
             To => $sitecfg{REMAIL},
             From => ($sitecfg{MAILFROM} || $htmlparams{email}),
             Subject => ($sitecfg{SUBJECT} || "Data Request"),
             Message => $message,
  );
  $mail{smtp}=[qw(localhost earth.co-ra.com)];
  $mail{retries}=$sitecfg{RETRIES}; 
  sendmail(%mail);

Basically, the code reads a message from a configuration file. In the message read are a few tags, such as <REQUEST>. Before this block, the code gathers some data and puts it in the message with the search/replace command. The message text is something like:

Here is the data you requested:\015\012<REQUEST>\015\012Data collected
+ on...

As I mentioned, when the message arrives in my inbox, the CRLF appears in text as "\015\012"
