Some users login fine, but, when they click on a message, they get an error. I a sucker for a pretty face, so I'd like to continue using it, but this makes it unfunctional. Thanks.
Betcha they are HTML mail messages. Unfortunately, there is a known issue with ISPConfig, the roundcube package provided, and html mail. Using the other mail client (uebimau or however it is spelled) with the "simple" skin (senti). See my note at teh bottom of the senti page if you install it...
The one I checked was not html actually, but you're saying there is no way to open an html email with roundcube on ISPConfig?
Correct, if it is the roundcube package that the ispconfig server serves up. roundcube installed "normally" on hosted webspace works fine, but does not do the nice mapping of [email protected] to local linux username for logins.
