The focus towards the final release of SME Server 6.5 is as it has always been in general for SME Server: Secure, reliable and easy to administate.
OK, then please tell me, why you have not updated openSSH and ZLib, which can be found in the smeplus script and there being considered as security fixes?
Other packages have been updated, but not to really newer versions, so I cannot check, if the security fixes have been included.
btw, the kernel version has changed in this Beta release
Sure:
-kernel-2.4.20-18.7.i386.rpm
+kernel-2.4.20-37.7.legacy.i386.rpm
Is any S-ATA support added here now?
Additionally, I think, that SMTP Auth towards the provider is very important, and since I have written an article about SME server for a german network magazine and have searched for a solution to send mails to the provider, which - at least in Germany - are using SMTP Auth, I can state, that there is no (legally available) solution to get this to work.
