Roundcube webmail tries to send mail from @127.0.0.1

This issue happens when you login to your roundcube webmail with your email ID only and not writing full email address with domain name, so it writes your identity in email from box as abc@127.0.0.1
If you log out and again login in with full user name including domain name, i.e abc@xyz.com then you can see your send email from is correct to you full email address and not abc@127.0.0.1.
So either you can always login to the webmail with full email address or do one change in the roundcube configuration to add your email domain to the login id automatically.
Go to the configuration folder of roundcube.
I am using iRedmail with default installations on Ubuntu, so my default path is located at /opt/www/roundcube/configs/defaults.inc.php
open this configuration file in text editor and uncomment the follwoing
$config[‘username_domain’] = ”;
after uncommenting add your email domain in the inverted commas, like below
$config[‘username_domain’] = ‘xyz.com’;
after making changes, restart the apache service
$sudo service apache2 restart (this is ubuntu command)
Now you should see your full email address in from list on roundcube webmail. Leave comment if it worked for you

a file I/O error has occurred while accessing vmware converter

While converting physical Windows 7 machine to Virtual machine of infrastructure type, I got this error. The error seems it is unable to read/write source or destination datastore.

I have installed VMware-converter-en-6.2.0-8466193 on Windows 7 physical machine with option locally selected. (not at server/client option)

All of my ESXi servers are connected to the vCenter Server, so I had to use vCenter Server's IP address to send this physical machine to the virtual world.

The issue i found was with the dns resolution to the vCenter Server's hostname. Since I am not using the same dns server on the Windows 7 client machine. So I updated the host entries manually for the vCenter Server's hosname to it IP address.

After adding dns eteries to the hostfile of windows 7, I am not getting this "a file I/O error has occurred while accessing vmware converter" and the migration has started.
