Thanks Andrew. You can post the patches to this list or if you decide to
do more work on the RoundCube code it's probably worth to add you as a
project member. This would give you access to the CVS repository (once
it is accessible again).

Just send me (direct mail) your SourceForge user name if you seriously
consider to contribute more code to RoundCube. Diff files are also
welcome for sporadic bug fixes.

These type of attachments are not included in forwards either, since the content disposition is not attachment... The following code in /program/steps/mail/ seems to prevent it:

Can I ask the development community for RoundCube -- what is the most effective way for for me to contribute to resolving issues such as these?  Posts like this?  Submitting bugs and diffs/patches via SourceForge?  Please let me know how best to do this.
