[horde] New lines are stripped from new messages composed in IMP

[Jose Perez]

Hi all:

I'm using Horde 3.3.3 and IMP 4.3.4 and having problems while
composing new messages in IMP with HTML format enabled: Newlines are
stripped from the message.
Is this an Horde or IMP problem? I've searching about this issue but I
only found some references related to a Horde 3.0.x bug, so that's a
little ancient.

Could somebody help me a little with this? Does anybody have the same problem?

Thanks a lot, bye people
