It would be useful if RoundCube contained functionality to retrieve messages from other POP3 / IMAP sources.
I have a number of e-mail accounts and as RoundCube is defintiely my favourite interface then I would much prefer to use this.
Great application by the way, I'm really happy that siteground have included this option. Can't wait for furture updates to be added to the 1.0 release which they currently have available.
