When you say "mailers" are you talking about emails? If so then you should
be using "\r\n" at all times since that's what numerous email-related RFCs
specify. If you use anything else then you may find your email gets rejected
by strictly implemented mail servers (rare these days, but it happens).
Incidentally, CR only applies to Mac OS9 and earlier. OSX uses LF due to its
BSD roots. For a near-complete list, see "Representations" here:
