Had to create DBD::mysql::dr::imp_data_size unexpe

If you receive the error message"Had to create DBD::mysql::dr::imp_data_size unexpectedly"

This is caused by an older version of the DBD::mysql module that is installed on your system. Generally, this can happen under older RedHat 7.X systems.

To resolve, uninstall the previous DBD module via RPM:

rpm -qa | grep DBD

First, locate if the DBD module is installed

rpm -e perl-DBD-MySQL-1.2219-6

Then uninstall/erase the selected RPM package.

Next, run the install.pl script of @Mail and the DBD::mysql module will be automatically installed.
