I thought it was strange because of this (a message id being interpreted
as an e-mail):

...GET /static/b169ed96a0dc55b4a76d1a29a1848ae3.css HTTP/1.1" 200 115911
"https://myhordeserver.xxx.xxx/imp/compose-dimp.php?to=20120917130155.Horde.Rgb1fEv4Cn9QV0lzuz0nzRA@myhordeserver.xxx.xxx&popup=1"
"Mozilla/5.0....

As if someone was trying to send an email to a message id. But Michael
Slusarz said this: "It looks like a Message-ID header from a message sent
by Horde/IMP is being interpreted as an e-mail address somewhere in
Horde/IMP. Looks like we are running the e-mail text search filter on the
Message-ID header when we don't need to (maybe in View All Headers in the
standard IMP view?) and a user is clicking on that.

Thanks
