Red Hat Bugzilla – Bug 65694
IMAP connections fail
Last modified: 2007-04-18 12:42:49 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc1) Gecko/20020417 Description of problem: After updating to RH73, a new bug popped up where PHP was checking the validity of the mail server certificate even for NON-SSL sessions. This was fixed, if you can call it that, by adding "novalidate-cert" to non-ssl mail server call string, even though this should not be necessary. This bug also appears to be triggered by updating to the latest php_imap and imap RPMs for Red Hat 7.2. It appears to be caused by compiling php_imap against imap-devel-2001c, so is possibly a bug in the IMAP libraries and not the IMAP server. Earlier versions of php_imap also exhibit this bug if recompiled against imap-devel-2001c. External IMAP clients (eg: Netscape communicator, MS Outlook) appear to be unaffected. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Any php_imap compiled against imap-2001c libraries as supplied in RH 7.3 or latest updates to RH 7.2. 2. imap_open ( {INBOX:443}, username, password ); -- fails 3. imap_open ( {INBOX:443/novalidate-cert}, username, password ); -- works Actual Results: Warning: cannot open IMAP stream. (PHP error message). Expected Results: Successful opening of IMAP connection. Additional info: Note that adding the /novalidate-cert option to non-SSL imap connections prior to imap-2001c appears to break them, eg: I get this error: source: email class.mail_msg_base.inc.php called from: /phpGroupWare/index.php, index_data() imap_last_error: Can't open mailbox INBOX: invalid remote specification
For the record, there is no such thing as imap-2001c, at least not released by Red Hat. Perhaps you've made a typo? Please confirm/correct, so we are on the same page. Assuming a typo... I would wager that this is not an imap package problem, but a php_imap problem.
The exact package name-version-release on Red Hat 7.2 is imap-2001a-1.72.0 The package on Red Hat 7.3 is imap-2001a-10 I agree that this could be a php_imap bug rather than an imap bug, but it seems odd that compiling php_imap against imap-2001a causes the problem whereas compiling it against imap-2000c-10 causes it to work correctly, whereas compiling it against imap-2001a causes it to break. It's not an imap server problem, since other IMAP clients are unaffected.
Has there been any action on this? It still appears to be outstanding and breaks most PHP based web mail systems.
Just because you compile something against one release of imap and it works, and compile it against another release of imap and it does not work, does not in any way lock it into being a bug in the imap server or sources. It is entirely possible that this software is misusing interfaces, or some interface has changed that should not have been used by software (such as internal interfaces). I've looked into this a bit, and I believe that it is a bug in the php software, not in UW imap. Without specific proof of a bug, and more troubleshooting and debugging information supplied in the bug report, it isn't worth wasting a lot of time debugging to find out in the end that I'm right. Please report this bug to the upstream maintainers of UW imap if you believe it is a bug in UW imap. I personally consider it a php webmail bug however, and suggest you report the problem to the authors of the php software you're using.
