At present only IMAP, POP3 and SMTP support login 23 options. For more information about login options please see RFC 2384, 24 RFC 5092 and the IETF draft 25 https://datatracker.ietf.org/doc/html/draft-earhart-url-smtp-00 26 27 Since 8.2.0, IMAP supports the login option `AUTH=+LOGIN`. With this option, 28 curl uses the plain (not SASL) `LOGIN IMAP` command even if the server 29 advertises SASL authentication. Care should be taken in using this option, as 30 it sends your password over the network in plain text. This does not work if 31 the IMAP server disables the plain `LOGIN` (e.g. to prevent password 32 snooping).
