can you post an original message (or fwd this email me at stepan.husak[a]solarwinds.com) that causing the problem, so we can try to reproduce this behavior?
I run circles around your bug, but still can't reproduce it...
- as we have some problems with handling <html> messages in old version, try do deselect option "HTML Email" in SuperFileSynchronizer email configurations.
- I think problem can be in character encoding (additional deutsch umlauts in your case). Can you change language to English in SuperFS preferences and check if result is the same?
- can your reproduce bug if you send the same message, with the same header, with the same attachments to AlertCentral but from email client (like Outlook, for example)? Or it must be SuperFS?
