L-Mail, or Lmail is short for "letter mail", and is a method of sending a real physical letter via an Internet web page.

An L-Mail system typically enables individuals and companies to send mail internationally directly from their computers, requiring only Internet access and a browser. In a first step, the user defines the letter format and then composes the text. Subsequently, the data is transmitted via a network to a printing centre chosen by the user, preferably in the vicinity of the addressee, where the letter is printed, put in an envelope and fed into the postal system.

Because letters are posted locally to the recipient, a faster speed of delivery can be achieved than by traditional air mail. With local postage being paid, costs can also be less than an equivalent air mail letter.
"I'm gonna send an L-Mail" means I'm going to send a real letter via a web site.
