IBM reference IBM Notes 9.0 Client Crashes after Launch or when Sending Mail

IBM Domino 9 is life since a long time and its relay a good version (stable).
A lot of customers ask me if there are is a reason against the update on the Server side.

And YES – if you are using a Domino smtp server – there is a „killer feature“.

There is a problem with the sending of attachments through a domino 9 smtp server, where attachments get corrupted or they are wrong „reattached“ so that the receipients gets confusied.

So please wait until Domino 9.0.1 to get this fixed.

Just be clear only for the Domino 9 smtp server !!!
