Application 21/12/2017 Thu 11:14:21 Error Error: The file exists
The HTML attachments are created with the date suffix so there are no chances of file being already present.
As per my observation if an attachment already exists in the output, it should be overwritten.
Before this error occurs, smtp server has sent close to 90 mails successfully and it throws this error randomly at different points of time on each day(Its a daily report).
