Hello,
How we can achieve the below requirement on Cisco ESA using message filter.
1.) Emails should only be sent from one specific source, with the below mentioned attachment format and attachment type of .pdf or .png only
2.) Emails should only be sent if the attachment is password protected.
Example:
File name format which should be attached with the eStatement email.
Subject : E-Statement
Attachment File Name : E-Statement.pdf
Sender Email : eStatement@xyz.com
Regards,
