Hi All, With the test I conducted lately I found that notification process causes this problem. In my setup I'm using unix domain socket notification. For the socket I'm using a domain socket created by Postfix which spawns a program written in PHP. (This setup I used because it's not possible write a server daemon with PHP).
So the final observation is that when I use notification and when an email comes with a large header (more than 2k bytes), delivery failes. But when the notification diabled, it works without any problems. I'm not sure whether this problem is caused by cyrus, postfix or my PHP program. Please see if this be due to a BUG in Cyrus Notification module. Thanks & Regards, Eranga
