[horde] Imp message search problem -- bug report & patch

[Michael M Slusarz]

Quoting "Daniel A. Ramaley" <daniel.ramaley at DRAKE.EDU>:

> As previously posted, i am setting up a webmail server with Imp 4.0.4 on

Yes, actually we do.  We query the server directly to determine  
whether it supports the charset parameter to the IMAP search call and  
then modify our subsequent calls to the IMAP server accordingly.
