Re: want my mail box on an external hdd

- What error did you get? Check /var/log/maillog and /var/log/dovecot/*.log please.
- Did you set correct owner/group/permission for the moved mailbox folder?

Re: want my mail box on an external hdd

Permission is root for the mail folder which is in the hdd and also the owner ship is root

about the logs you asked for, i am unable to write them all down here as forum has a limited space. Should i kind of give u a link or something for all the logs?

Re: want my mail box on an external hdd

/var/vmail/vmail1 must be owned by user/group "vmail:vmail", with permission 0700.

I moved the vmail to a folder. Mounted the hard disk at /mount/ubuntu/maail     /new is just a folder and inside it is the vmail.

I have redone all the permissions taking this as a reference:https://forum.iredmail.org/topic14652-help-need-to-move-the-varvmail-directory.html


Please reply asap I need to set it up asap. And thanks for replying till now!

Re: want my mail box on an external hdd

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....

Re: want my mail box on an external hdd

Alright again i called up someone near to serve and asked to reboot and the ssh suddenly started to work. Here is the output that you asked:

drwx------ 3 vmail vmail 4096 Nov 18 05:44 /mount/ubuntu/maail/new/vmail1
drwxr-xr-x 3 vmail vmail 4096 Nov 19 03:40 /mount/ubuntu/maail/new
drwx------ 4 ubuntu ubuntu 4096 Nov 18 08:19 /mount/ubuntu/maail
drwxr-xr-x 3 root root 4096 Jan 28  2018 /mount/ubuntu
drwxr-xr-x 3 root root 4096 Jan 28  2018 /mount

I guess is it that i have to change the ownership of all of them to vmail:vmail and permission to 0700??? Is that what is wrong here?

Re: want my mail box on an external hdd

UPDATE:
tried creating the whole scene in a virtual box, created a new virtualbox with ubuntu 18 LTS server os.
Mounted a virtual a hdd at /media/demo/maail
moved the vmail1 folder to the mounted location
Given the permission, ownership that you have already told to and also created the symlink

and it still gives the same error......

Also tried moving the vmail1 folder simpy to desktop, that worked very well. I didn't even had to change the ownership for that!

I tried moving  vmail1 and the whole vmail folder but the results were the same as above in both the cases....

Please help!!!

This directory permission is the problem. With 0700 on /mount/ubuntu/maail/, only user "ubuntu" can access this directory. That's why "vmail" user can not access /mount/ubuntu/maail/new/vmail1.

You should set it to 0755 on /mount/ubuntu/maail. If "/mount/ubuntu" is some user's HOME directory, you'd better mount "vmail1" to other directories like /mnt/vmail.

/mount/Ubuntu/maail

Re: want my mail box on an external hdd

When i was installing iredmail, it asked me if i want to also install netdata to monitor traffic on my server. I selected it to install.

Now when i try to access domain.com/netdata it just pops a dialog box to enter user id and pass.

In the end of configuration of iredmail it didn't told me what are the credentials for netdata.

Any idea about that??

Re: want my mail box on an external hdd

It uses the postmaster@<first-mail-domain> and its password by default. You should be able to find it in file iRedMail-0.9.9/config.

Re: want my mail box on an external hdd

my hostname -f is mail.domain.com

so you mean to say the username will be "postmaster@mail" and password will be same as i enter in iredadmin?

correct??

20

Re: want my mail box on an external hdd

It's "postmaster@<your-first-mail-domain-name>", the first mail domain name is the one you inputed during iRedMail installation, it's NOT your server hostname.

Re: want my mail box on an external hdd

Hey Zhang, you may close this thread as for a few days I won't be able to check up the server. I will start a new one if needed.
And thanks for all the help!
