Thank you Tom for the reply.
SLF file was copied to /opt/Symantec/Licenses folder but it don't create a cert.pem file.
Now im having new problems.
When i register it says that it cannot register the specified license file. I downloaded a new slf file but still same error exists.
And also, when I login to my server (https://localhost:41443/brightmail) its says that the certificate was expired.
Sorry if im giving you a headache.
Thank you.
