Hi,
don't really use email/webmail function on my box. But, after seeing your post, I decided to enable it & give it a try. I did run into a problem with a horde authentication error.
Try following Michael Soulier's suggestions in this thread:
http://forums.contribs.org/index.php?topic=20210.msg79505#msg79505It corrected the login problem for me, but again, I haven't done any extensive testing to see if horde is functioning properly as I don't normally use this feature.
Also, you may want to post additional info so people may better assist you.
i.e. which version of SME you're running, other contribs and/or setting changes.
Hope this helps,
Walt
