[CentOS] How to add ClamAV to Postfix?
I sent this email to the Rehdat list, but I thought the Centos users might be more inclined to have the command-line solution I am looking for, so I thought I would post it here too: I would like to add anti-virus to my email server. Currently I have Postfix, Dovecot, PHP, and Squirrelmail installed. The users only use Squirrelmail to access mail. I am looking for command-line instructions, since I have limited access to the server itself (I am using SSH). ClamAV seems to be most common linux AV package, so I assume I should be using that. I'm not sure if I should be using Amavisd or MailScanner, or neither. I believe I need one of them to act as the glue that connects Postfix to ClamAV. Apparently none of these packages (Amavisd/MailScanner/ClamAV) are part of RHEL5, so I have to get the RPMS from somewhere else. Is there some standard way of adding AV to Postfix? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I can try those instrutions, but I had been scared off by the authors initial disclaimer: "Dear Reader, this howto hasn't been updated since 2006 and has some parts which are missing. You may end up installing a non-working postfix but I believe it can help you to guide through the installation steps if you know what you are doing:)" Or perhaps there was another link from postfix.org? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] How to add ClamAV to Postfix?
I was able to get everything working after getting the appropriate RPM's from "EPEL". I'm new to RH/Centos, so I did not know about that site. I tweaked the config based on what I found here: http://fedorasolved.org/server-solutions/postfix-mail-server I know this was not really a Centos question, but thanks for you guys helping me anyway. thanks! ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Is there a web-based server status package?
I have a small squirrelmail server using Postfix & Dovecot, and I would like to add a web-based "status" screen to remotely check its health. Is there a preferred packaged for doing this?

I'll get it from EPEL, since it is Fedora-sponsored. On Tue, Mar 24, 2009 at 2:53 PM, Florin Andrei wrote: > Marko A.

[CentOS] Limiting maildir sizes with Postfix?
I have a small Squirrelmail server, using Postfix & Dovecot. I am trying to limit the amount of mail a user can get. The "mailbox_size_limit" value does not seem to be being honored. I am using the Maildir directory format. >From googling, it appears that "mailbox_size_limit" applies to a single file (mbox format?), and that it does not work with Maildirs. Is this correct? How should I limit the Mailbox size of the users? I'm not very familiar with Linux "quotas", but I think that is my only other choice. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Cannot set user quotas
Hello, I am having some trouble getting quota's to work. When I try to set the quota for a user, it does not show up when I run repquota. I am doing this on a Redhat (RHEL5) machine (I assume it is the same on Centos). I think I am missing a step, but this is what I am doing: (1) I add usrquota to the /etc/fstab file, then reboot LABEL=/home /home ext3 defaults,usrquota 1 2 (2) Verify /home is /dev/hda3 /sbin/tune2fs -l /dev/hda3 | grep volume Filesystem volume name: /home (3) Create the user quota file quotacheck -cmu /home ls –l /home/aquota.user repquota /home [r...@mail ~]# repquota /home *** Report for user quotas on device /dev/hda3 Block grace time: 7days; Inode grace time: 7days Block limitsFile limits Userusedsofthard graceused soft hard grace -- root -- 184224 0 0 4 0 0 12345 -- 208 0 0 49 0 0 54321 -- 172 0 0 40 0 0 (4) Turn on quotas quoataon /home (5) Add a user quota setquota -u 12345 1 11000 0 0 -a /dev/hda3 (6) Recalculate the quotas quotaoff /home quotacheck -amu quotaon /home (7) Check if the quotas are active ls –l /home/aquota.user repquota /home [r...@mail ~]# repquota /home *** Report for user quotas on device /dev/hda3 Block grace time: 7days; Inode grace time: 7days Block limitsFile limits Userusedsofthard graceused soft hard grace -- root -- 184224 0 0 4 0 0 12345 -- 208 0 0 49 0 0 54321 -- 172 0 0 40 0 0 (8) Shouldn't the limits look like this: ???

Re: [CentOS] Cannot set user quotas
I think my problem was that because I am using all-numeric usernames, setquota was assuming I was giving it a UID. So I used the "-x" option and now it is working: setquota -x 12345 1 11000 0 0 -a /dev/hda3 On Wed, Apr 22, 2009 at 9:52 AM, Xn Nooby wrote: > edquota show's the quota, but the quota command does not: > > [r...@mail ~]# setquota -u 12345 1 11000 0 0 -a /dev/hda3 > > [r...@mail ~]# edquota -u 12345 > Disk quotas for user 12345 (uid 12345): > Filesystem blocks soft hard inodes > soft hard > /dev/hda3 0 1 11000 0 > 0 0 > ~ > ~ > > [r...@mail ~]# quota -u 12345 > Disk quotas for user #12345 (uid 12345): none > > > On Wed, Apr 22, 2009 at 9:38 AM, Xn Nooby wrote: >> Hello, I am having some trouble getting quota's to work.
