EMail Backup: lm-backup.tar.gz: No such file or directory

[Erwin van der Zwart]

Hi Habib,

The new FW 1.2 for SL and 1.5 for HL requires a change in the mail script.

1) Make sure you have changed your g-mail account to enable HL to send e-mail on https://www.google.com/settings/security/lesssecureapps
2) Change user and password in the script
3) Change sender and receiver details in the script

Code:
