[imp] UNable to view any emails after upgrade of horde, imap and lz4 today to latest in Group Edition Webmail 5

[info at interpost.biz]

Hello,

I am unable to view any emails after upgrade of horde, imap and lz4 
today. It looks like it times out when trying to display a message. But 
it never displays.
The error messages states connection to IMAP server lost.

Can I provide you with any additional info to help resolve this 
problem?

Best,

ed
