>> Today I had to use another client machine at a different location

>>
>> - I logged in to H5, got the portal view (dynamic), current emails  
>> etc were listed
>> - I clicked to see my inbox, but got a Horde report about a severe  
>> server error "with details in the log" (the log reported that the  
>> e-mail server wouldn't support secure connection)
>>
>> - logout, login -> get portal as above
>> - click "reload page" button of browser: no emails, no dates, etc.  
>> and Horde's log fills with "e-mail server doesn't support secure

>>
>> My first guess were cookie problems, so I deleted all cookies for

Hi Arjen,

thanks for your reply... then I'm neither crazy nor alone :D FWIW,  
we've had no change on the related systems (DB, web servers) during my  
switch to the other location. User prefs are stored in imap (Kolab)  
here, but that wasn't changed either.

Well, I'll keep my eyes open!

Thanks again,
Jens
