I am having two virtual machine:
The first is for php pages and web access.
The second one contains a hmailServer.
Both are situated in a production environnement and can be accessed via internet and also via local network.
The problem is when i use imap_open in PHP to connect to hmailserver via imap, the time to execute is not stable, from 300 ms to over 4 seconds.
What do you think the problem is
An example
$p=imap_open("ip}INBOX","emailadress","password");
var_dump($p);
imap_close($p);
When i ran this code from an external server, it works and takes always about 300ms.
