Rejected File Types
MS office documents, executables, other potential harmfull files
How to send the file which is one of the rejected file types but is really no harm and safe?
The sender can modify the file extension with a file type that can pass through our services. For example, the sender can rename a file form “abc.exe” to “abc.xxx“. Once the file is received, the recipient can save the attachment and rename it back to “abc.exe“. However, the email will still be rejected if the attachment is classified as a virus or malicious software and no matter what file type of the attachment is.
