While cobbling together my first PHP email form, I forgot to do the wordwrap() call to trim my message lines to 70 characters, before doing the mail() call. I only realized my mistake after viewing a few examples of email forrms, where a comment line would always say "// message lines should not exceed 70 characters (PHP rule), so wrap it". Well the bottom line is this.. If I do the wrap, it will. But if i don't, it won't wrap, and it doesn't seem to hurt anything. Indeed, I've copied text with long paragraphs into my mail form as a test, and it gets delivered exactly as I'd want, with line breaks only between the paragraphs. So is this a now obsolete rule?
