Yes, thanks to the free open and gratis qualities.

It depends.

Patching Mail::IMAPClient module is better done in CPAN than in imapsync
public release.

Patching Mail::IMAPClient module with this RFC break is better done in
your local imapsync than in imapsync public release.

I maintain the position taken in
http://www.linux-france.org/prj/imapsync_list/msg00159.html

RFC: "In all cases, SP refers to exactly one space.  It is
NOT permitted to substitute TAB, insert additional spaces,
or otherwise treat SP as being equivalent to LWSP."

The danger in supporting such a bug is that we don't know what
can be broken in other cases. So fix it for yourself
and welcome in free, open, gratis software and support.

Thanks for your feedback.
