hook before retrive_password() mail is sent

Hey guys,
I would like to have one more hook.

retrieve_password()
\theme-my-login\includes\class-theme-my-login.php (l 1001)

For multisites it’s necessary to change e.g. network_home_url() to home_url(), if you want to use the plugin on all network pages.

Otherwise the link to the new-password-form will always be the same domain, instead of the site’s domain, where you filled out the form.

So a hook just before the mail is sent or an option on wp-admin would be great.

Thanks in advance
Nick
