Specify the login options to use during server authentication.
You can use login options to specify protocol specific options that may be used during authentication. At present only IMAP, POP3 and SMTP support login options. For more information about login options please see RFC 2384, RFC 5092 and the IETF draft https://datatracker.ietf.org/doc/html/draft-earhart-url-smtp-00
Since 8.2.0, IMAP supports the login option AUTH=+LOGIN. With this option,
curl uses the plain (not SASL) LOGIN IMAP command even if the server
advertises SASL authentication. Care should be taken in using this option, as
it sends your password over the network in plain text. This does not work if
the IMAP server disables the plain LOGIN (e.g. to prevent password
snooping).
