regarding my horde installation it says NOW memory_limit disabled: No If PHP's internal memory limit is turned on and if not set high enough Horde will not be able to handle large data items (e.g. large mail attachments in IMP). If possible, you should disable the PHP memory limit by recompiling PHP without the "--enable-memory-limit" flag. If this is not possible, then you should set the value of memory_limit in php.ini to a sufficiently high value (Current value of memory_limit: 64M). # Mcrypt Support: No MIME Magic Support (fileinfo): Yes Mcrypt is a general-purpose cryptography library which is broader and significantly more efficient (FASTER!) than PHP's own cryptographic code and will provider faster logins. # memcached Support (memcache): No The memcache PECL module is needed only if you are using the memcached SessionHandler. See horde/docs/INSTALL for information on how to install PECL/PHP extensions. memory_limit disabled: No If PHP's internal memory limit is turned on and if not set high enough Horde will not be able to handle large data items (e.g. large mail attachments in IMP).
