Bug #18282 Updated: imap_open return doesn't return FALSE when mailbox doesn't exist

ID: 18282 Updated by: valerio@dei.unipd.it Reported By: valerio@dei.unipd.it Status: Bogus Bug Type: IMAP related Operating System: Linux PHP Version: 4.2.1 New Comment: Sorry, but I don't think so. The function names are imap_open() and imap_reopen not imap_connect(). If mailbox doesn't exist imap_lasterror() return an useless nil. During an IMAP transaction when you act a "SELECT" on a unexisting mailbox you get an error: . select alskj . NO SELECT failed: Can't open mailbox alskj: no such mailbox Probably there is a weakness in how open_mail() in lib c-client return streams. Talking about my workaround ... suppose you have thousands of mailbox...it's not so optimized to check all of them just to open one. Then suppose that between imap_listbox and imap_reopen the file vanished. What would you get? The script output an empty page.

In your test script, the connection is established, just the mailbox select fails. Try add this right after the imap_open() line: echo imap_last_error(); ------------------------------------------------------------------------ [2002-07-12 04:22:25] valerio@dei.unipd.it This script output nothing (I mean _nothing_) when mailbox with name "this_file_doesnt_exist" isn't there. <?php print "BEFORE IMAP_OPEN<br>"; $my_stream=imap_open("{localhost:143}this_file_doesnt_exist","realusername", "rightpassword",OP_READONLY); if ($my_stream) { /* uncomment me if you want to see $my_stream value */ /*print $my_stream; */ $barney=imap_fetchbody($my_stream,1,"1"); print $barney; imap_close($my_stream); } print "AFTER IMAP_OPEN<br>"; ?> My current workaround is a imap_open("{localhost:143}",...,OP_HALFOPEN), imap_listmailbox and comparison on all values to check the existence of a particular mailbox name before opening it. ------------------------------------------------------------------------ [2002-07-11 14:21:35] sniper@php.net Please give us a short but complete example script which can be used to reproduce this.. ------------------------------------------------------------------------ [2002-07-11 14:12:23] valerio@dei.unipd.it imap_open($server_strings.$mailbox, $username,$passwd,$options) should return FALSE when username/password are correct but mailbox doesn't exist. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18282&edit=1
