When I enable mod_pagespeed without any exotic configurations (running Debian, Apache 2.2, WP 3.5.2, memcached), Postie stops fetching email either when triggered by cron or my grabbing the get_mail.php, and when I try to get the get_mail or try to initiate it from within wp-admin, Chrome gives me no data received, Apache's access.log shows no hit, the error log offers nothing that I can see as useful (though will paste if that would help). When trying to run Postie with debugging, it doesn't create the wp-content debug file.
Can postie and pagespeed simply not play nice together or is there some tweak I could add either to postie or pagespeed? Might this be something like caching or rewriting of the get_mail.php by pagespeed that could be prevented with a line or two in the pagespeed conf or .htaccess? Thanks..
