Title: Delete User/Mailbox - Hard-disk space not correct?
Post by: dbuechel on June 02, 2016, 08:17:36 AM: Hey,

I have a big problem with our Hard-disk space when I delete a user account.

Example:
Our Hard-disk space have when 46G - Used 9,4G

I create a user and over fetchmail start the connect to a pop3 account and download over 23500 emails ;)

Then I have 25G used hard-disk space - all ok.

But now, when I delete the user over the server-manager, it delete the mail account on the hard-disk but my Hard-disk space have used 17GB

This is a different from 7.6G from start the user account!

What will not be deleted?
What can I do to clean up the hard drive?

Post by: Stefano on June 02, 2016, 08:47:14 AM: Do you have alwaysbcc enabled? Did you forward emails to other accounts?
Title: Re: Delete User/Mailbox - Hard-disk space not correct?
Post by: dbuechel on June 02, 2016, 08:56:14 AM: No - there is only one user account maillog and the admin account.
Title: Re: Delete User/Mailbox - Hard-disk space not correct?
Post by: Stefano on June 02, 2016, 08:57:55 AM: Well.. Check users' quota, maillog make me think you have alwaysbcc enabled
Title: Re: Delete User/Mailbox - Hard-disk space not correct?
Post by: dbuechel on June 02, 2016, 09:16:46 AM: Really - I've tested the now twice with a fresh installation.
I create only the user maillog, and run fetchmail.

There is only ONE user folder:
/home/e-smith/files/users/ => admin

And I don't use this:
=> Keep a copy of all emails

config setprop qpsmtpd Bcc enabled
signal-event email-update

Post by: brianr on June 02, 2016, 10:40:17 AM: In my experience deleting files in Linux does not always free the space instantly, I guess the garbage collection is run as a background task. I'd have expected it to complete with an hour or so though.

I think we'd need to see the evidence ("df" and "du" before and after)?

In my experience deleting files in Linux does not always free the space instantly, I guess the garbage collection is run as a background task.

There's no garbage collection running as a background task.

There are two cases where space won't be freed when you delete a file. One is where there are multiple links to a file (i.e. where there are two or more directory entries, but only one file), and the other is when there is a process running which has an open file descriptor to the file - in which case the file becomes an anonymous file (i.e occupies space, but has no directory entries). When the last process which has an open file descriptor closes the descriptor, or exits, then the space will be freed.

Mail left in /var/spool/qpsmtpd

This is a good case where qpsmtpd/clamd should be using anonymous files, so that it doesn't accidentally leave temporary files around (for example, if it crashes). An anonymous file is one which is opened, then deleted immediately while an open file descriptor is kept, so that data can be written to and read from the file.

Title: Re: Delete User/Mailbox - Hard-disk space not correct?
Post by: dbuechel on June 03, 2016, 08:38:54 AM: Hi,

I made yesterday following:

Delete all fils in /var/spool/qpsmtpd over MC

Create the user Maillog again.
Create fetchmail to our server and start the service.

In the beginning everything looked good. Message has been scanned and then deleted.

Fetchmail was ever 15 minutes to check.

This morning the following:
Webmail tell me 23829 Emails.

In /var/spool/qpsmtpd => 22868 files !!!

But!
Quote
fetchmail[25935]: 23842 Nachrichten (23837 gesehene) für

Different from 5 mails.

When I look in my thunderbird - 23842 is correct - but ONE Email is unread!

This email is ~70 MB big - only 13 jpg-files.

I look in Webmail from SME -Server and search this email - he don't download it.

But fetchmail download other emails with big attachment. - see picture.

I found something interesting:

Title: Re: Delete User/Mailbox - Hard-disk space not correct?

When I look in my thunderbird - 23842 is correct - but ONE Email is unread!

This email is ~70 MB big - only 13 jpg-files.

I look in Webmail from SME -Server and search this email - he don't download it.
That's not surprising. 70MB is well over the default size limit

Then please open a bug, and you'll be asked for specific information so we can track, and fix the issue

Post by: dbuechel on June 03, 2016, 09:11:51 AM: For the limitation of emails, it's 15MB by default. - correct?

I increase
Code: [Select]
config setprop qmail MaxMessageSize 100000000
Title: Re: Delete User/Mailbox - Hard-disk space not correct?
Post by: dbuechel on June 03, 2016, 09:37:14 AM: I make now the following:

I delete the user maillog.
I delete all files in /var/spool/qpsmtpd

I deactivated over server-manager the function - check email with antivirus.

Then:
I create the user maillog again - start fetchmail.

You shouldn't have. You'd better open a bug when the problem exists so devs can analyze and fix it
