Hi, I am getting this error message when I try to sent a attachment that is just a little bigger than 1 Mb. Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 1791797 bytes) in /opt/local/apache_ssl/htdocs/horde/imp/compose.php3 on line 621 I would like to know how do I customize this allowed memory size. My users need larger attachment space. Thanks, José
