problems with setting up some POP 3 accounts

[zimbrowse]

hallo,

i've just downloaded the latest version of YZD and started to use this fantastic application. i had no problems setting up my yahoo account. but i don't seem to be able to set up all my POP 3 accounts. YZD works fine with one of my POP 3 accounts, but with others not. i get the the following message when trying to set up the account: service.FAILURE: system failure: Unable to connect to IMAP server.
because i know it works (at least in one case) i'm a little bit helpless. does any one else have the some problems?

regards ,
