Hello,

I have having trouble isolating what is causing my daily email of rkhunter report to only contain gibberish. The email has 32 lines that look like random characters. eg

ICAgICBbIE5vIHVwZGF0ZSBdCiAgQ2hlY2tpbmcgZmlsZSBiYWNrZG9vcnBvcnRzLmRhdCAg
ICAgICAgICAgICAgICBbIE5vIHVwZGF0ZSBdCiAgQ2hlY2tpbmcgZmlsZSBpMThuL2RlICAg


On my server, the rkhunter logs look ok. eg rkhunter -C

Any input is greatly appreciated.
Thankyou.

For anyone experiencing the same issue.

The solution was to use a different email viewer. eg Thunderbird

Thunderbird does not display the report in the email body, it offers it as an attached text file.
