If you have a system which uses xinetd instead of inetd, have you made sure that you have made the correct corresponding xinetd changes for those services?
Try telneting to the server port (143 for IMAP, 110 for POP3). If you get a “refused” error, that probably means that you don’t have the service set up in inetd.conf. If the connection opens and then closes with no message, the service is set up, but either the path name of the server binary in inetd.conf is wrong or your TCP wrappers are configured to deny access. If you don’t know how to make the corresponding changes to these files, seek the help of a local expert for your system.
