lpoht has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I'm writing code which sends e-mail using Mail::Sendmail and am having a small problem. When I send the message with newline characters (\n in this case), they're not interpreted as newlines in the e-mail client. I'm using Evolution e-mail, but am having the same problem in Outlook on a Windows box. What's the trick here? Thanks

    The 'trick' is to know that most internet protocols require lines to be separated by CRLF. According to RFC 2822 (Internet Message Format): 
    Messages are divided into lines of characters.  A line is a series of 
+characters that is delimited with the two characters carriage-return 
+and line-feed; that is, the carriage return (CR) character (ASCII val
+ue 13) followed immediately by the line feed (LF) character (ASCII va
+lue 10).  (The carriage-return/line-feed pair is usually written in t
+his document as "CRLF".)

    CRLF is \015\012, note that \n cannot be relied on to always be a newline.

      Thanks for the information about CRLF, but I'm not quite sure how to actually send these characters. Simply sending them in ASCII text as "\015\012" in the e-mail doesn't work, and they are interpreted as that string. I've searched around this and other sites and have found no answer yet. How can I send them so they are interpreted as a CRLF?

        That should work.. (It's how CRLF is defined in Socket.pm) - Maybe you should post some of your code so we can see exactly what you're doing?

        C.
