comment Configure Citadel to be Used For sending email using smtp
What do you mean by: "Now i want to use it to send emails from outside like using php."? I don't know what "from outside" means nor do I understand "like using PHP".

Since H/W is mentioned as a possibility, have you run a memory tester such as memtest86+ overnight?

Sorry, I have no ACL filesystems to work with at the moment so no output to practice with...

You can substitute another data line for owner in the egrep argument if you like.

comment find nouser equivalent for POSIX ACLs
On my Linux system, "user:" lines show permissions like "rwx". The following can be used to combine lines (thanks to stackoverflow.com/questions/8545538/…): find . -name '*.jpg' -exec getfacl {} \; | egrep 'file|owner' | sed -rn 'N;s/\n/ /;p'

comment find nouser equivalent for POSIX ACLs
Something like: find . -name '*.ext' -exec getfacl {} \; | grep "owner: [0-9]" If that works I'll make it an answer. :)

comment find nouser equivalent for POSIX ACLs
If find -exec getfacl results in an output distinctive to non-existent users (like a number instead of the user name), the results could be piped into a regular expression searching for this pattern. I would try it but I'm not about to create non-existent users just to find out.

comment child pid 29281 exit signal Segmentation fault (11)
The PID is psuedo-random and can be ignored. Segmentation fault indicates a broken program or library mismatch. The backtrace is of the parent process noticing the death of a child process. If you can capture the backtrace or error logs of the child process that is crashing, you will have more useful information.

comment How is DNS resolved for email addresses?
There are two questions here. Using a different mail server is as simple as setting up another account or changing the mail server of the existing account. Mail clients' behavior differs wildly. Perhaps you can tell us what mail clients you are using, and if you have control over your DNS service.

comment Firewall Connections fail to open under load
Please edit your question to tell us: what systems (O/S), applications are involved. How did you discover the Firewall was the cause? What firewall is being used? Also the log file for Firewall should be a separate question, and can probably be answered by a simple search.

comment Error getting sendmail to properly send emails from AWS EC2 server (domain of server address does not exist)
Yahoo has stringent anti-spam requirements if you desire to deliver directly to their users. Among them are reverse DNS lookup. If this is the problem, another tactic can be to deliver mail to a recognized server, such as your company or customer's mail server, and have that forward to Yahoo. The intermediate mail server would simply have to accept mail from the EC2 machine, after that it should know what to do.

comment Postfix Configuration files
"One place" can mean under one directory tree, not necessarily in one directory. If the customer is not file system savvy it is doubtful they can give you useful direction at this detailed level. That is where a consultant's expertise comes into play. Don't ask questions about implementation. Ask questions about requirements.

comment What should be the ideal home directory permissions in linux
I would not recommend group write permission for a personal home directory. Maybe a shared service "drop box" for a pseudo-user's home dir, but there are better ways to implement that.

comment OS X Lion machines will continually query Active Directory 2008 for every user in the directory
I would look at two things. 1. Look carefully at the ldap query and filters on the client side. Experiment. 2. See if any job is running on the OS X systems that requires user information. Try to track the LDAP query down to the requesting service.

comment How do you backup 40+ Centos5.5 servers?
This might be possible with Clonezilla, a PXE server and some creative scripting. This link has some details, but is not exactly the process you are looking for. The key to good boot image creation is that it can't be live, it has to be static. openlogic.com/wazi/bid/188051/…

comment How do you backup 40+ Centos5.5 servers?
Restore consists of replacing bad disks, booting the G4L or Clonezille and restoring the image. Then you have to catch up on any updates made since then, but at that point you have a working system, with a working backup/restore client installed, such as NetBackup.
