PHP Bug Type: IMAP related
Bug description: imap_open retries 3 times on failed auth
Description:
------------
imap_open will retry 3 times on bad credentials. Some IMAP or POP servers
delay on successive bad logins, making a failed imap_open take very long.
Worse, some servers will lock the user out because of repeated failed
login attempts.
Somewhere during module initialization, this call needs to be made:
mail_parameters(NIL, SET_MAXLOGINTRIALS, (void *) 1);
Reproduce code:
---------------
imap_open("{mailserver/pop}", "user", "badpass");
Expected result:
----------------
It should try logging in only once.
Actual result:
--------------
It tries logging in three times (watch with a packet sniffer or strace).
