Hi, I am running ispconfig 3.1 on ubuntu 14.04 with nginx as web server. I have some php code that needs to collect emails from another mail server (not on the same server as ispconfig). the code is: $inbox = imap_open($hostname,$username,$password) or die('Cannot connect to mail server: ' . imap_last_error()); When I execute the script I get the following error: Fatal error: Call to undefined function imap_open() in /var/www/clients/... phpinfo() doesn't show that the imap extension is loaded, so the error makes sense. My question is, how can I load the php imap extension so I can use it on the script. Thanks!
