smtplib documentation of mail_options/rcpt_options does not cover key-value case

smtplib's sendmailand send_message support the arguments mail_options and rcpt_options which both take a list of ESMTP options. However, the documentation does only describe the single word case not the key-value case.

The caller may pass a list of ESMTP options (such as 8bitmime) to be used in MAIL FROM commands as mail_options. ESMTP options (such as DSN commands) that should be used with all RCPT commands can be passed as rcpt_options.

To determine the correct format, users need to read the library source code. Maybe this could directly be extended to:

The caller may pass a list of ESMTP options as strings (such as "8bitmime") to be used in MAIL FROM commands as mail_options. ESMTP options (such as DSN commands) that should be used with all RCPT commands can be passed as rcpt_options (such as "NOTIFY=SUCCESS,FAILURE").

Commencez par la documentation de smtplib concernant sendmail et send_message, puis comparez les descriptions de mail_options et rcpt_options avec le code source de la bibliothèque. Le travail est terminé lorsque la documentation décrit clairement à la fois les options ESMTP autonomes et les options clé-valeur, avec un exemple tel que NOTIFY=SUCCESS,FAILURE.
