After recent cpanel update, I started getting the following error while accessing horde webmail.

This problem is expected to be fixed before cPanel 11.51 becomes 11.52 and is published to CURRENT, but it is still occurring in the 11.51 build that is in EDGE right now. The temporary fix for that problem is as follows.

Now, move or remove any files that are listed by the above find commands...

Sometimes your might need to check for detailed logging in email. One of my friends was  developing an email application and he wanted to check what was happening behind the screen when he received an email, moves it to another folder, deletes it etc.

Hence, we decided to enable detailed logging in imap. It was a cpanel server and we used the option imapdebug. Always keep a backup of the file you edit.

Now touch a file named  imaplog.txt at the root of the account where you want to enable logging. Restart the courier service. Suppose I need to enable logging for greproot@abc.com.

I wanted to transfer my entire sites from my Windows Plesk server to Linux Cpanel server. I could simply create the new accounts in the new server and copy the files. The main issue was with emails. My windows server was using mail enable, where as the the cpanel server uses exim.

I realized I will have to create all email accounts manually in the new server. A simple tool which will do everything in a click was not available. Losing email was not something I could let happen, so I decided to go ahead with creating accounts and then copying emails. I used imapcopy for it. If anybody wants to do it, you can do it as follows. I am copying the email account test@abc.com to new server. Its password is test123c on both servers.

One of my friends email account was hacked, and was used to send tons of spam mails. Some of the mails were sent direct from his account while some others where spoofed.  There were around 50K emails in the queue.

I cleared all mails sent from him with the following command.

where abc@abc.com is the account that was hacked.

Still there were close to 49000 mails in the queue. I wrote the following script to clear them. It basically checked the auth_id field in the header section of every email in the queue and if it matches abc@abc.com, then delete the message from the queue.

Last day a few domains started throwing incorrect disk usage in WHM. The accounts has a lot of files, but the disk usage was reported as 0 in List Accounts section. Upon checking noticed that someone had played with the fstab and /home was not mounted with usrquota correctly. Did the following to correct it.

Alternatively, you can reboot the machine, so that the changes will be picked up from the fstab after making changes.

When it is executed,...

Sometimes while running upcp in a cpanel server, you may encounter the following error and upcp will quit.

***** FATAL: Could not write to /etc/yum.conf

Check if any attributes are set for /etc/yum.conf.

You can check it by issuing the following command.

If you get the following error while running easyapache in a cpanel server, it means httpd is not enabled in service manager.

To correct it, do the following.

Now try running easyapache again.

When you access fantastico from cpanel, if it is displaying a blank page, it can be fixed easily.

Now refresh your fantastico page and enjoy 🙂

I had been trying to upgrade my cpanel version with upcp last day.

My current version – 11.34

Targetted version – 11.38

Tried many times, but each time it was stuck after the following error.

Upon searching, I identified the problem is with the SQLite module. So I killed the currently running process, updated sqlite and ran again and hurrayyyy it worked.

cpan -i CPAN::SQLite   - install the cpanel sqlite module directly

/scripts/up...

Sometimes you won’t be able to send/receive emails. Telnet may mention a temporary problem as follows.

Upon checking the error log, I noticed the following error displayed.
