    It really is. I have no idea where to edit this setting.
    FYI: I use MfE 2.09.158 (the built-in version) because I had problems with 3.x (no zimbrabackend problems I think)

    For me OK! Zimbra is the master!

    OK, i am trying to use exchange on iphone with zimbra backend. When configuring an exchange account on my iphone using rev 27, i get this error in the log:
    [Thu Apr 01 08:18:01 2010] [error] [client 166.137.9.113] PHP Fatal error: Call to undefined function curl_init() in /srv/www/htdocs/sites/z-push/backend/zimbra.php on line 131

    Here is line 131-136 of said zimbra.php:
    $this->_curl = curl_init();

    curl_setopt($this->_curl, CURLOPT_URL,$this->_server);

    curl_setopt($this->_curl, CURLOPT_POST, true);

    curl_setopt($this->_curl, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($this->_curl, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($this->_curl, CURLOPT_SSL_VERIFYHOST, false);

    Needless to say, i am unable to sync email,calendars or contacts

    It was not installed so i installed php5-curl and then attempt to "get mail" in the exchange account i have setup for this This has to be a configuration error (on the iphone), right? Or as i stated earlier in this thread that we do not use the standard 80 port for zimbra. Therefore, our zimbra url in the zimbra.config looks like this, http://domain.here: port. I have tried:
    http://server.domain.here: port
    http://domain.here
    http://server.domain.here

    What should this string look like?

    I think i've found a workaround or a solution...

    increase in php.ini memory_limit from 16M to 256MB and everything works fine...

    I assume that these last two sections are imposing an arbitrary limit of 1MB on emails that will sync.

    However, if an email reaches that limit, the sync should be capable of continuing with other emails in the inbox.

    Hopefully someone can figure out what is making it break here.
    The problem with large messages is related to the Mail_mimeDecode::decode function (located in include/mimeDecode.php). Depending on what you have set in your PHP.INI file for maximum memory, if it hits the maximum in this function, it just stops. And the memory needed is much more then the message size.

    This post on the Z-Push forums talks a little more about it. If anyone with PHP programming knowledge would be willing to look into this and see if there is a way to tweak this to use less memory or if you can write a new function that isn't so dependent on memory that we could incorporate into the backend, it would be much apperciated. You can contact me directly if you have questions.

    I've just bumped into this memory limit too - well done gnosbush! All sorted and back in-sync.
