Probably resolving a hostname to IP address via DNS.

At an application level, not sure. Maybe sending an email via the VAX/VMS MAIL command.

EDIT: Actually...hmm. If it was actually MAIL, it might have been using DNS to do an MX resolution, looking up a mail server for a given domain, not resolving a hostname.
