I have been using the egroupware locally on my machine for over a year now and I've never had any issue with any email configuration.
I just decided to host my copy in cloud with godaddy but I've been getting the error in subject everytime I try to configure IMAP and SMTP settings. I could not even get past setting up one of the protocol.
I don't know if any other person out there has experienced any issue like this.
Thanks in anticipation.
