Hello,
i've the "IMAP doesn't exist. PHP must be compiled with IMAP enabled." Problem as many others too. The question i've regarding this issue - why doesnt it simply work to install php5-imap in Debian instead of recompile whole php which i dont want todo - obviously.
mail_imap() works like a charm and i've also read that one can do "yum install php-imap" to get the functionality needed by osticket.
Kind regards
