This function has been deprecated.
This function will report the date of the last login for all mailboxes on a domain that are either active or inactive (whichever is selected by the API user). POP3/IMAP/Webmail logins are all considered a login (not SMTP Auth). Last login information is recalculated nightly-- so the most recent login should generally be yesterday's date on an active account.
Three strings, an integer, and one result array:
Administrative username, Administrative password, Domain name, Active flag (integer, 1=active, 0=inactive)
Last login array (as in: list="user1, month/day/year hour:minute:second AM/PM",list="user2..."...)
If successful, the return value of the function will be 1.
Consult the Result Code Table for a list of result codes and their meaning.
