SMTP: Simple Mail Transfer Protocol
The SEND, SAML, and SOML verbs
SEND, SAML, and SOML
are just like
The only difference is that
This profusion of verbs serves no purpose;
the concept of a mailbox is already broad enough to
include any type of delivery that the recipient wants to set up.
SEND, SOML, and SAML are rarely implemented in practice.
- MAIL requests delivery to the recipient's mailbox;
- SEND requests delivery to the recipient's ``terminal'';
- SOML (``send or mail'') requests delivery to the ``terminal''
if that is available, otherwise the mailbox;
- SAML (``send and mail'') requests delivery to the ``terminal''
if that is available and to the mailbox.
