University of Michigan IT Central Services


RSUG operates the University of Michigan IMAP and POP servers. This service is available for free to all faculty, staff, students and for a fee to alumni of the University of Michigan. To find information regarding quotas please check the updated site at Your account

Accounts are assigned machines based on the first letter of the account name. E.g. the user bjensen would be assigned to the host b.imap.itd.umich.edu. Most configurations work best with these single letter hostnames.

The current mapping of letters to real hostnames is as follows:

  • a tremors.imap.itd.umich.edu
  • b alien.imap.itd.umich.edu
  • c mimic.imap.itd.umich.edu
  • d species.imap.itd.umich.edu
  • e species.imap.itd.umich.edu
  • f critters.imap.itd.umich.edu
  • g alien.imap.itd.umich.edu
  • h critters.imap.itd.umich.edu
  • i gremlins.imap.itd.umich.edu
  • j nightbreed.imap.itd.umich.edu
  • k leviathan.imap.itd.umich.edu
  • l screamers.imap.itd.umich.edu
  • m relic.imap.itd.umich.edu
  • n leviathan.imap.itd.umich.edu
  • o predator.imap.itd.umich.edu
  • p predator.imap.itd.umich.edu
  • q predator.imap.itd.umich.edu
  • r critters.imap.itd.umich.edu
  • s gremlins.imap.itd.umich.edu
  • t screamers.imap.itd.umich.edu
  • u gremlins.imap.itd.umich.edu
  • v screamers.imap.itd.umich.edu
  • w alien.imap.itd.umich.edu
  • x predator.imap.itd.umich.edu
  • y predator.imap.itd.umich.edu
  • z leviathan.imap.itd.umich.edu
  • The current reverse mappings:

  • b g w alien.imap.itd.umich.edu
  • f h r critters.imap.itd.umich.edu
  • i s u gremlins.imap.itd.umich.edu
  • k n z leviathan.imap.itd.umich.edu
  • c mimic.imap.itd.umich.edu
  • j nightbreed.imap.itd.umich.edu
  • o p q x y predator.imap.itd.umich.edu
  • m relic.imap.itd.umich.edu
  • l t v screamers.imap.itd.umich.edu
  • d e species.imap.itd.umich.edu
  • a tremors.imap.itd.umich.edu
    • These mappings change, though infrequently.
