* Add email-based password reset Fixes #734 * rename SETPASS to RESETPASS * review fixes * abuse mitigations * SENDPASS and RESETPASS should both touch the client login throttle * Produce a logline and a sno on SENDPASS (since it actually sends an email) * don't re-retrieve the settings value * add email confirmation for NS SET EMAIL * smtp: if require-tls is disabled, don't validate server cert * review fixes * remove cooldown for NS SET EMAIL If you accidentally set the wrong address, the cooldown would prevent you from fixing your mistake. Since we touch the registration throttle anyway, this shouldn't present more of an abuse concern than registration itself.

SET modifies your account settings. The following settings are available:`,

`$bENFORCE$b
|
|
'enforce' lets you specify a custom enforcement mechanism for your registered
|
|
nicknames. Your options are:
|
|
1. 'none' [no enforcement, overriding the server default]
|
|
2. 'strict' [you must already be authenticated to use the nick]
|
|
3. 'default' [use the server default]`,

|
If 'multiclient' is enabled and you are already logged in and using a nick, a
|
|
second client of yours that authenticates with SASL and requests the same nick
|
|
is allowed to attach to the nick as well (this is comparable to the behavior
|
|
of IRC "bouncers" like ZNC). Your options are 'on' (allow this behavior),
|
|
'off' (disallow it), and 'default' (use the server default value).`,
|
|
|
|
`$bAUTOREPLAY-LINES$b
|
|
'autoreplay-lines' controls the number of lines of channel history that will
|
|
be replayed to you automatically when joining a channel. Your options are any
|
|
positive number, 0 to disable the feature, and 'default' to use the server
|
|
default.`,
|
|
|
|
`$bREPLAY-JOINS$b
|
|
'replay-joins' controls whether replayed channel history will include
|
|
lines for join and part. This provides more information about the context of
|
|
messages, but may be spammy. Your options are 'always', 'never', and the default
|
|
of 'commands-only' (the messages will be replayed in /HISTORY output, but not
|
|
during autoreplay).`,
|
|
`$bALWAYS-ON$b
|
|
'always-on' controls whether your nickname/identity will remain active
|
|
even while you are disconnected from the server. Your options are 'true',
|
|
'false', and 'default' (use the server default value).`,
|
|
`$bAUTOREPLAY-MISSED$b
|
|
'autoreplay-missed' is only effective for always-on clients. If enabled,
|
|
if you have at most one active session, the server will remember the time
|
|
you disconnect and then replay missed messages to you when you reconnect.
|
|
Your options are 'on' and 'off'.`,
|
|
`$bDM-HISTORY$b
|
|
'dm-history' is only effective for always-on clients. It lets you control
|
|
how the history of your direct messages is stored. Your options are:
|
|
1. 'off' [no history]
|
|
2. 'ephemeral' [a limited amount of temporary history, not stored on disk]
|
|
3. 'on' [history stored in a permanent database, if available]
|
|
4. 'default' [use the server default]`,
|
|
`$bAUTO-AWAY$b
|
|
'auto-away' is only effective for always-on clients. If enabled, you will
|
|
automatically be marked away when all your sessions are disconnected, and
|
|
automatically return from away when you connect again.`,
|
|
`$bEMAIL$b
|
|
'email' controls the e-mail address associated with your account (if the
|
|
server operator allows it, this address can be used for password resets).
|

As an additional security measure, if you have a password set, you must
