SoCS hosts a mail server to handle incoming and outgoing mail for the school of computer science. It is hosted at mail.socs.uoguelph.ca which is an alias for owlery.socs.uoguelph.ca. The system primarily handles mail for @socs.uoguelph.ca addresses, but will also process @cis.uoguelph.ca for legacy reasons, and @mail.socs.uoguelph.ca.
