A number of issues can affect this, some of which are:
- assuming your canonical address is seibercom.net, that
  maps to 174.109.28.112, so your traffic needs to go through your
  router which will route it back into your internal network.
- your router may be blocking the imap port, one (or more) of:
  $ grep -i imap /etc/services 
  imap2  143/tcp  imap  # Interim Mail Access P 2 and 4 
  imap2  143/udp  imap
  imap3  220/tcp        # Interactive Mail Access
  imap3  220/udp        # Protocol v3
  imaps  993/tcp        # IMAP over SSL
  imaps  993/udp
- you don't have the port forwarded in your router's NAT table.
- I don't use IMAP; but many servers restrict access to the local network
  unless configured otherwise (such as adding 0.0.0.0, or specifying the
  interface(s) allowed)
