# Some refactoring to get the exception handling for sendmail with UTF8 option
|
||
|
|
# centralized and also to get ability to unit test. This file should eventually move
|
||
|
|
# to py/splunk library as we move out additional duplicate work from sendemail.py and
|
||
|
|
# sendemail_handler.py into this file for better encapsulation, and maintenance.
