Subject: New ShareMon Link Created |
|
|
|
Hello, |
|
|
|
A new file has been uploaded. You can access this file for 24 hours at the following link: |
|
https://${share_server}/${1} |
|
|
|
Please be aware, anyone who has this link will be able to access this file. If the contents are sensitive, please consider encrypting the zip file before you upload it, and sharing the encryption key by a separate method, like phone, fax, or encrypted email. |
|
|
|
Thanks, |
|
The IT Script Gremlin |
