Hey, thanks for replying but here is another problem and now i am pretty sure iredmail is causing it. Sometimes like now i am unable to ssh to my server. This happens only after installation of iredmail. And it's not that every time it happens. Sometimes on a simply reboot ssh starts working and else connection is refused.
Have any solution for this? Cause now to see the permissions of the dir you have asked for i will have to go to the server and it's a bit far away....
