FIX

The issue occurred due to the server hostname, if you are hosting the domain in plesk the same name should not be included as the hostname.

# cat /etc/hostname
yourhostname.com
# vi /etc/postfix/main.cf

*********************
Incorrect line

#mydestination = yourhostname.com, localhost.net, localhost, localhost.localdomain
*********************
change from above to

mydestination = $myhostname, localhost.net, localhost, localhost.localdomain

Now check. The issue should be fixed. :)

SVN: File remains in conflict

This error occurs when you didn't update the SVN and try to commit changes or, someone has made changes to this file that are conflicting with your changes. There are two ways to handle this situation. Either, you can revert back the changes you want to commit and then, update the SVN and after that make the changes again and commit.
