Hooks

$Plugin->addHook('hook.name', 'functionName');

Login

login.credentials.step-1

params:
	string &$sEmail

Happens in resolveLoginCredentials($sEmail) BEFORE resolving domain name.
This is the pure text from the login screen (DoLogin) or the SSO feature (ServiceSso) received by LoginProcess().
- DoLogin() -> LoginProcess() -> resolveLoginCredentials($sEmail)
- ServiceSso() -> LoginProcess() -> resolveLoginCredentials($sEmail)
So $sEmail can just have the value `test` without a domain.

login.credentials.step-2

params:
	string &$sEmail
	string &$sPassword

Happens in resolveLoginCredentials($sEmail) AFTER resolving domain name.
So $sEmail always has a domain (for example `test` is now `test@example.com`).

login.credentials

params:
	string &$sEmail
	string &$sImapUser
	string &$sPassword
	string &$sSmtpUser

	$sEmail is the domain imap->fixUsername() without shortening.
	$sImapUser is the domain imap->fixUsername() for login into IMAP.
	$sSmtpUser is the domain smtp->fixUsername() for login into SMTP.
