Hello everybody,
currently we are using roundcube at http://webmail.ntua.gr/, serving more than 35 mail servers in our university and we are extremely happy with it.
There is a bug reported by users that affects certain messages when forwarded, or replied, inline. These messages contain an HTML part (just it or plus an alternative plain part and other attachments). When forwarding or replying and "Compose HTML messages" is set to "never" the HTML part is used but several pieces of the text are missing.
Such a message, slightly modified, is available at:
http://noc.ntua.gr/~christia/tmp/message.txt
The pieces of text dropped out are the ones that are highlighted blue in the HTML part. It has, probably, something to do with roundcube's HTML parser and the fact that the syntax of the HTML part contains many errors.
Tested in versions 0.8-RC and older (back to 0.5).
Regards, Panagiotis
