Why do mail server care about how long a line is? Why don't they just let the client reading the mail worry about wrapping the lines?

This is how email work(ed) over smtp. When each command was sent it would get a '200'-class message (success) or 400/500-class message (failure). Sound familiar?

telnet smtp.mailserver.com 25

HELO

MAIL FROM: me@foo.com

RCPT TO: you@bar.com

DATA

blah blah blah

how's it going?

talk to you later!

QUIT

I like how SMTP was at least honest in calling it the "receipt to" address and not the "sender" address.

Edit: wrong.
