Hi Everyone, My CentOS 4.4 mail server is having problems sending mail after updating it to 4.4 Before the update, I did not have any problems. My ISP requires that email clients must authenticate to their mail servers before mail can be sent out. I setup smtp auth to get postfix to relay mail through the ISP's mail servers. Here's my config: main.cf -------- relayhost =

Does anyone know how to get procmail and dovecot to play happily together with mboxes? I'm on Centos 6.5, fully patched. I'm getting tons of lock timeouts which is killing performance. I tried using dovecot's lda from procmail, which prompted many adjustments to selinux, which I managed, but it still gives permission problems, and I haven't succeeded in getting it to deliver

I have a raid 50 array on a 3ware controller. The box is running centos 6.5 and the file system is ext4. I'm going to try some other filesystems, but could anyone suggest any alternative raid setups as well as stripe sizes I should try? The old server uses the same controller on a centos 5.10 setup, using ext3, and it performs much faster i/o. The old 3ware setup is raid 5. -chuck --

Question for the list: I have a small, aircooled pc server, which is running fine, but the log gets filled with a series of messages saying the package, and each of 8 cpus is throttled because of thermal issues. Then, within the same second according to the timestamps, it reports everything is OK and throttling is off. This happens once every minute. In reality, when I try performance

I did a complete clean install of CentOS 5 from CD yesterday. I took the default selinux configuration. After that I ran yum update and found 600 plus updates and installs. I let it go to do the updates and during that process I saw a large number of issues in the selinux troubleshooter. I also see these kinds of things in /var/log/messages: **Unmatched Entries** (Only first 10 out of 49031

Hi, I am trying to get a CentOS 6 system relaying mail via my G-Mail account. I followed the instructions found at https://www.zulius.com/how-to/set-up-postfix-with-a-remote-smtp-relay-host/but there seems to be a problem with authentication. I have done some research but still can't get this working. Any suggestions ? It seems the user and password are correct. Dec 27 23:15:36 hbc

I have a centos 6.6 laptop which is having trouble (intermittent boot failures, or more rightly so, multiple failures, intermittent booting). The laptop is running selinux. I pulled the second internal disk out to get my data off of it. I plugged it into my centos 5.x machine and mounted it. I was able to do a dir listing, but whrn I tried to cd into any of the directories, I get a bunch of AVC

I've recently built a new mail server with centos6.5, and decided to bite the bullet and leave SELinux running. I've stumbled through making things work and am mostly there. I've got my own spam and ham corpus as mbox files in /home/user/Mail/learned. These files came from my backup of the centos 5 server this machine is replacing. The folder is owned by the user (the following is

How to get postfix working on CentOS 6 and Comcast. Recently, they've changed their policies regards email relay and require authentication even to send email. (they no longer use IP address ranges, presumably in an attempt to curb outgoing SPAM) I didn't see an updated howto anywhere on the Interwebs, thought I'd point out what I had to do. The part that had me stumped for longer

Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP. I would like *@example.com (everything) to go to virtual at example.com, where virtual is a valid virtual user.
