Setup using the http://howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04 setup guide.

I have posted a fix for Gusty that also works for Hardy http://www.howtoforge.com/forums/showthread.php?t=19765
I replaced that line and then reloaded and restarted postfix, but still I am getting a blank alert. User also still not getting the alert.
Each user should have a maildirsize in their directory that keeps track of the quota info. The problem I found was this file was not there. As root do the following commands: Code: updatedb Code: locate maildirsize You see somthing like this in the output: /home/vmail/domain.com/user1/maildirsize If you open the file in an editor you should see something like this: 26214400S 7309923 766 The 26214400S is the quota limit The 7309923 is current amount of space used The 766 is number of emails (sent & received) in the user directory. If this file or info does not exist, you will continue to receive blank emails.
The command Code: locate maildirsize returns nothing. I am guessing that would be an issue. Tried searching quickly to find how to resolve, but no luck. I will keep looking, but if you have an idea for this. Also, I am using virtual users with MySQL. I didn't know if locate maildirsize was trying to look at my user account. Thanks again.
After aplying the QuotaPatch to Postfix, Postfix should create this file when the next email arrives. Then every time an email is received (or removed via an imap client), Postfix should update this file. So the problem should be in Postfix or the QuotaPatch. The line I change is per the Patch instructions, from their website. The only thing I can think of, if you did an upgrade, then the original, or newer, version of Postfix may have been installed. That means the patched version was uninstalled.
I tried to follow the process to patch the current version 2.5.1 Code: mail_version = 2.5.1 milter_macro_v = $mail_name $mail_version doesn't appear to hav changed anything, but I got errors at the end of building the package: Code: mailbox.c: In function âchange_mailbox_limitâ: mailbox.c:90: error: âvirtual_mailbox_limit_mapsâ undeclared (first use in this function) mailbox.c:90: error: (Each undeclared identifier is reported only once mailbox.c:90: error: for each function it appears in.) mailbox.c: At top level: mailbox.c:140: error: redefinition of âchange_mailbox_limitâ mailbox.c:75: error: previous definition of âchange_mailbox_limitâ was here mailbox.c: In function âchange_mailbox_limitâ: mailbox.c:150: error: âvirtual_mailbox_limit_mapsâ undeclared (first use in this function) mailbox.c: At top level: mailbox.c:174: error: redefinition of âchange_mailbox_limitâ mailbox.c:140: error: previous definition of âchange_mailbox_limitâ was here mailbox.c: In function âchange_mailbox_limitâ: mailbox.c:189: error: âvirtual_mailbox_limit_mapsâ undeclared (first use in this function) make: *** [mailbox.o] Error 1 make: Leaving directory `/usr/src/postfix-2.5.1/src/virtual' make[1]: *** [update] Error 1 make[1]: Leaving directory `/usr/src/postfix-2.5.1' make: *** [build] Error 2 It has not been updated and I was fairly sure it was already patched. Where else could I look to find out why this isn't creating the file?
I tried rebuilding Postfix with the patch per falko's guide. It worked twice without any errors. If you are sure that the quota patch is in place, then you can try to use my main.cf file. It is straight from the guide with a few spam settings added. The file is from a working mail server using Ubuntu 8.04 and has delivered quota reports daily since being placed into service June 1, 2008. Copy your main.cf file to main.cf.old so you can copy it back if needed. Remove the main.cf file and replace it with the one below. You will have to change the parts in bold to fit your server name. (I think there are only 2 instances.) Then reload postfix and send an email to your account on the server. Then do: Code: updatedb Code: locate maildirsize If the quota patch is installed and working, you should see something like this: /home/vmail/your_domain.com/your_user/maildirsize If you see this then do: Code: /usr/local/sbin/quota_notify Also remember, if a user has not used 1% of the quota or more, they will not show in the report.

Negative values? I was trying to troubleshoot this issue of mine where I'd get negative % for some users in my report. 1. I changed my /etc/postfix/main.cf from: Code: virtual_mail[COLOR=Red][B]box[/B][/COLOR]_extended = yes to: Code: virtual_mail[COLOR=Red][B]dir[/B][/COLOR]_extended = yes as suggested in some other thread and run: Code: /etc/init.d/postfix reload 2. I renamed each 'maildirsize' file for each user to 'old.maildirsize' 3. I sent an email to all users. 4. Checked after a while and some of them had the 'maildirsize' file created while others not. 5. Run: Code: /usr/local/sbin/quota_notify and got a report that seemed ok. 4. Created a blank 'maildirsize' file for the users that didn't have one. 5. Sent a new mail to all users and run the report script. 6. Got a report that seemed ok again. 7. Checked some of the 'maildirsize' files and some of them had 2 lines for space used and nr of emails. The second line had negative values!?!: Code: 104857600S 135416 62 -1728 -1 Any ideas???
http://www.usenet-forums.com/courie...ge-mailboxes-quotas-3gb-more-maildirsize.html That could be because of files > 2GB.
resolved Must have been something wrong with the files i had downloaded. I used a different directory, downloaded the source and patch following the guide, installed and all is working perfectly now. Thanks for the help.
