Playing arround with the beta feature multiple accounts I added some E-Mail accounts - a mix of IMAP & pop3 accounts. e.g GMX pop3 works fine. But there is one pop3 (non SSL) account that can not be accessed. Following error message will be displayed when accessing this account.

POP3 CAPA command failed: -ERR authorization

Propably this is a problem of the '1 per month' email hosting account - the CAPAbility command is described here http://www.ntmail.co.uk/kb.htm?q=981
